Two cars start simultaneously from points A and B, 120 km apart, and meet after 2 hours. If the speed of one car is 50 km/h, what is the speed of the other?
Show answer & explanation
Correct answer: A
Explanation
Combined speed = Total distance / Time
= 120 / 2
= 60 km/h
Speed of one car = 50 km/h
Speed of the other car = 60 - 50 = 10 km/h
