Dialogue: 0,0:00:20.64,0:00:22.41,Default,,0000,0000,0000,,So the test begins at 1:59.
Dialogue: 0,0:00:22.41,0:00:25.12,Default,,0000,0000,0000,,So it's a very strange\Ntime to begin a test,
Dialogue: 0,0:00:25.12,0:00:26.29,Default,,0000,0000,0000,,but let's just go with that.
Dialogue: 0,0:00:26.29,0:00:28.63,Default,,0000,0000,0000,,So let me draw a\Nlittle time line here.
Dialogue: 0,0:00:28.63,0:00:35.03,Default,,0000,0000,0000,,So let's say that\Nthis is 2 o'clock PM.
Dialogue: 0,0:00:35.03,0:00:37.65,Default,,0000,0000,0000,,Then we're going\Nto have 3:00 PM.

Dialogue: 0,0:00:49.96,0:00:51.44,Default,,0000,0000,0000,,So this is volleyball practice.

Dialogue: 0,0:00:57.00,0:00:58.85,Default,,0000,0000,0000,,So let me continue\Nthe number line.
Dialogue: 0,0:00:58.85,0:01:02.53,Default,,0000,0000,0000,,So this right over\Nhere is 1:00 PM.
Dialogue: 0,0:01:05.88,0:01:10.90,Default,,0000,0000,0000,,So the test is going to begin at\N1:59, so 1 minute before 2 PM.
Dialogue: 0,0:01:10.90,0:01:12.95,Default,,0000,0000,0000,,We know that there are\N60 minutes in an hour.
Dialogue: 0,0:01:12.95,0:01:16.46,Default,,0000,0000,0000,,So 1:59 is 1 minute\Nbefore 2:00 PM.
Dialogue: 0,0:01:16.46,0:01:18.21,Default,,0000,0000,0000,,So I'm not drawing it\Ncompletely it scale,
Dialogue: 0,0:01:18.21,0:01:24.64,Default,,0000,0000,0000,,but this right over\Nhere is 1:59 PM.
Dialogue: 0,0:01:24.64,0:01:29.22,Default,,0000,0000,0000,,So we use 1 minute\Nto get to 2:00 PM.
Dialogue: 0,0:01:29.22,0:01:32.44,Default,,0000,0000,0000,,And then, let's see, we have\Nto get up to 96 minutes.
Dialogue: 0,0:01:32.44,0:01:36.43,Default,,0000,0000,0000,,So then you get another 60\Nminutes to go to 3:00 PM.
Dialogue: 0,0:01:36.43,0:01:39.58,Default,,0000,0000,0000,,So, so far, we've\Nused a cumulative 61.
Dialogue: 0,0:01:39.58,0:01:40.65,Default,,0000,0000,0000,,So this is 1 minute.
Dialogue: 0,0:01:40.65,0:01:42.57,Default,,0000,0000,0000,,So this is how long the\Ntest has been going on

Dialogue: 0,0:01:43.40,0:01:48.36,Default,,0000,0000,0000,,So 1 minute by 2:00 PM,\N61 minutes by 3:00 PM.
Dialogue: 0,0:01:48.36,0:01:52.22,Default,,0000,0000,0000,,If we go all the way to 4:00 PM,\Nthat's going to be another 60.
Dialogue: 0,0:01:52.22,0:01:56.11,Default,,0000,0000,0000,,That'd be 121 minutes, which\Nis longer than the actual test.
Dialogue: 0,0:01:56.11,0:01:58.95,Default,,0000,0000,0000,,So we know that the\Nentire test is 96 minutes.
Dialogue: 0,0:01:58.95,0:02:00.66,Default,,0000,0000,0000,,So we're going to get\Nto some point right

Dialogue: 0,0:02:03.14,0:02:06.03,Default,,0000,0000,0000,,That's 96 minutes.
Dialogue: 0,0:02:06.03,0:02:09.59,Default,,0000,0000,0000,,And what we need to figure\Nout is, is what is left over?

Dialogue: 0,0:02:12.36,0:02:14.49,Default,,0000,0000,0000,,Or what is this\Ntime, this difference
Dialogue: 0,0:02:14.49,0:02:15.69,Default,,0000,0000,0000,,in time right over here?
Dialogue: 0,0:02:15.69,0:02:17.18,Default,,0000,0000,0000,,And so to figure\Nthat out, we had
Dialogue: 0,0:02:17.18,0:02:19.95,Default,,0000,0000,0000,,to figure out the time at\Nwhich 96 minutes have passed
Dialogue: 0,0:02:19.95,0:02:21.95,Default,,0000,0000,0000,,since the beginning of the exam.
Dialogue: 0,0:02:21.95,0:02:25.09,Default,,0000,0000,0000,,So at 3 o'clock, 61\Nminutes have passed.
Dialogue: 0,0:02:25.09,0:02:27.50,Default,,0000,0000,0000,,And so if we, if we say\Nwell how many more minutes
Dialogue: 0,0:02:27.50,0:02:29.43,Default,,0000,0000,0000,,have to go on for\Nthe end of the test?
Dialogue: 0,0:02:29.43,0:02:32.42,Default,,0000,0000,0000,,It's going to be 96 minus 61.
Dialogue: 0,0:02:32.42,0:02:36.60,Default,,0000,0000,0000,,So the amount of time that\Nelapses past 3 minutes
Dialogue: 0,0:02:36.60,0:02:40.93,Default,,0000,0000,0000,,is 96 minus 61,\Nwhich is 35 minutes.
Dialogue: 0,0:02:40.93,0:02:48.72,Default,,0000,0000,0000,,So this right over here\Nis going to be 3:35.
Dialogue: 0,0:02:48.72,0:02:50.80,Default,,0000,0000,0000,,And so now our question\Nis, how much time is there
Dialogue: 0,0:02:50.80,0:02:55.80,Default,,0000,0000,0000,,between 3:35 and 4:00 PM?
Dialogue: 0,0:02:55.80,0:02:58.95,Default,,0000,0000,0000,,Well, once again, 60\Nminutes in an hour.
Dialogue: 0,0:02:58.95,0:03:02.02,Default,,0000,0000,0000,,4:00 PM is essentially\Nthe 60th minute.
Dialogue: 0,0:03:02.02,0:03:09.36,Default,,0000,0000,0000,,So if we take 60\Nminus 35, we get 2:25.
Dialogue: 0,0:03:09.36,0:03:15.30,Default,,0000,0000,0000,,So she has a total of 25\Nminutes remaining after the test
Dialogue: 0,0:03:15.30,0:03:17.58,Default,,0000,0000,0000,,before she has to get\Nto volleyball practice.
Dialogue: 0,0:03:17.58,0:03:18.56,Default,,0000,0000,0000,,Just as a review.
Dialogue: 0,0:03:18.56,0:03:21.66,Default,,0000,0000,0000,,One minute between 1:59\Nand 2:00, then another 60.
Dialogue: 0,0:03:21.66,0:03:23.87,Default,,0000,0000,0000,,That gets us to\N61 total minutes.
Dialogue: 0,0:03:23.87,0:03:30.16,Default,,0000,0000,0000,,Then another 35 minutes gets\Nus to 96 minutes have passed.
Dialogue: 0,0:03:30.16,0:03:32.81,Default,,0000,0000,0000,,And that also gets\Nus to 3:35, which
Dialogue: 0,0:03:32.81,0:03:37.26,Default,,0000,0000,0000,,means we have 25\Nminutes until 4:00.
