How long will it take a car 3m long travelling at 100km/h to overtake a truck 10m long travelling at 50km/h, if the car is 10m behind the truck
Answered by Steve
Since you mention the length of the car and truck, I assume that you want the rear of the car to pass the front of the truck.

So, the rear of the car is 3+10+10=23 m from the front of the truck.

At a relative speed of 50 km/hr, that will take

23m/(50km/hr * 1000m/km) = 23/50000 hours

I'll let you convert that to seconds.

Distance=3+10+10=23

relative speed=100-50=50m/s =13.89m/s

Time=Distance/Relative speed=23m/13.89s=1.656 seconds
