Question #60630

Two cars traveling in opposite directions pass each other at 1:00 p.m. One of the cars travels at a speed of 90 km/h, while the other travels at a speed of 72 km/h. How far apart will they be at 2:00 p.m.?

A) 162 km B) 108 km C) 144 km D) 180 km

A) 162 km B) 108 km C) 144 km D) 180 km

Expert's answer

The relative speed of the cars:

V = V1 + V2 = 90 + 72 = 162 km/h

By 2:00 pm they will be travelling for one hour. Therefore, the distance will be:

D = V x t = 162 x 1 = 162 km

Correct answer option: A) 162 km
