Question
Two cars, 'A' and 'B,' are heading towards each other on
a straight road. Car 'A' is traveling at a speed of 56 km/h, while Car 'B' is moving at 34 km/h. Initially, they are 450 meters apart. Determine the time required for the two cars to meet.Solution
Combined speed of cars 'A' and 'B' = 56 + 34 = 90 km/h = 90 X (5/18) = 25 m/s So, required time = 450 ÷ 25 = 18 seconds Hence, option d.
