Two roads intersect at an angle of 48º. A car and truck collide at the
intersection, and then leave the scene of the accident. The car travels at
100 km h down one road, while the truck goes 80 km h down the other road.
Fifteen minutes after the accident, a police helicopter locates the car and pulls it over. Twenty minutes after the accident, a police cruiser pulls over the truck. How far
apart are the car and the truck at this time?

Same cosine law as I just showed you.
Except in this case you have to calculate the lengths of the two sides.
But that is easy, aren't you given the time and speed?
Remember distance = time x speed.
