00:00:00.440 --> 00:00:02.379 A:middle L:90%
The first thing we can do is construct a triangle
2
00:00:02.379 --> 00:00:04.849 A:middle L:90%
to help us understand what we're solving for this problem
3
00:00:08.339 --> 00:00:10.330 A:middle L:90%
. Obviously, we know that this is south and
4
00:00:10.330 --> 00:00:12.849 A:middle L:90%
this is West. Just given the compass using the
5
00:00:12.849 --> 00:00:16.000 A:middle L:90%
pipe Bagram the arm X squared plus y squared equals
6
00:00:16.010 --> 00:00:18.210 A:middle L:90%
X squared expired just in. Troubled by the car
7
00:00:18.210 --> 00:00:20.629 A:middle L:90%
after time t Well, we can write this as
8
00:00:20.640 --> 00:00:26.190 A:middle L:90%
two acts D x over DT Let's do why do
9
00:00:26.190 --> 00:00:31.620 A:middle L:90%
you Why over DT equals to us de ass over
10
00:00:31.620 --> 00:00:36.850 A:middle L:90%
DT decks over duty is 25 you're overdue to 60
11
00:00:37.240 --> 00:00:39.990 A:middle L:90%
. Therefore we have asked is squared of X squared
12
00:00:39.990 --> 00:00:44.630 A:middle L:90%
plus y squared putting in 50 squared plus 1 20
13
00:00:44.630 --> 00:00:52.170 A:middle L:90%
squared, which is 1 30 It's no substituting and
14
00:00:52.170 --> 00:01:12.329 A:middle L:90%
values to our original equation. We got GS over
15
00:01:12.329 --> 00:01:18.450 A:middle L:90%
DT This 65 units is miles per hour
