Question

Two cars start at the same time from the same location and go in the same direction. The speed of the first car is 50 km/h and the speed of the second car is 60 km/h. The number of hours it takes for the distance between the two cars to be 20 km is

Answer 1

Answer:

Speed of car A - 40km/h

speed of car B - 60km/h

distance = speed × time

distance covered by car A = 40 × 3hrs

= 120kms

distance covered by car B = 50 × 3hrs

= 150kms

difference between car B and A

= 150kms - 120kms = 30 kms.

Thus, car B is 30 kms ahead / far than car A
