Question

Two cars leave the same station at the same time, moving along straight tracks that form an angle of 30°. If one car travels at an average speed of 50 km/hour and the other at an average speed of 60 km/hour, how far apart are the two cars after two hours?

Answer 1

If one of the car is driving 0 degree forward, and the second car is driving 30 degrees forward, then after two hours, we can use:

tan 30degrees = x/100

x = 100 tan 30degrees

x = 57.735km
