A car travelling at 60 km/h overtakes another car travelling at 42 km/hr. Assuming each car to be 5.0 m long, find the time taken during the overtaking and the total road distance used for the overtake?

Solution

Total distance to be travelled for overtaking the car = 5.0 +5.0 = 10. 0 m
Relative velocity of first car w.r.t second car = 60 - 42 = 8 km/hr
= 8 x 1000/ (60 x 60)
= 50 m/s
Time taken, t = 10/5 = 2 s.
Road distance used for overtaking = distance travelled by first car in 2 s + length of first car
= [ 60 x 1000 / (60 x60)] x 2+ 5
= 38.33 m
