Question

Two cars travelling in parallel lanes at 90 kph and 72 kph. Assuming each car to be 5 m long, find the
time taken during the overtake and the total road distance used for the overtake

Answer 1

Answer:

Speed of the cars is 90 kmph = 25 m/s and 72 kmph = 20 m/s.

You have not given the initial separation between the cars. assume it to be 100 m.

Length of each car = 5 m

Total distance = 100 + 5 + 5 = 120

Time required for overtake = (120)/(25 - 20) = 24 seconds
