00:01
In the position we are giving the directions that is west and another is north.
00:10
Okay, so one car is moving towards west at speed of 50 miles per hour.
00:19
Okay, this is car a and another car is moving towards north at speed 60 miles and this is car b.
00:29
Now we are given a situation where car b is at a distance of 0 .4 miles from the intersection point and car a is at a distance of 0 .3 miles.
00:45
Okay, and we have to find how fast is this cars approaching towards itself.
00:52
This is origin o.
00:55
This is point p, let, and this is point q.
00:59
So in triangle p .oq, we have let this be theta, okay.
01:12
So this is 90, so this angle will be 90 minus theta.
01:18
Okay, so in triangle pqo, 10 theta is equal to 0 .4 divided by 0 .3.
01:29
3.
01:30
Okay.
01:31
So, which is equal to 4 divided by 3.
01:35
Okay, so this implies theta value will be equal to 53 degree...
