We know that the car is traveling at 95 km/hr and the truck is driving at 75 km/hr. To find the answer we have to setup the expression solving for total time t. We know that at the end, the distance traveled by both the car and truck will be equal, so the expression will have the cars speed on one side and the truck's on the other. The distance ahead of the truck has to be converted to km since it is in m and doing that we get .210km. Now, we get the following: (95 km/hr * x) = (75 km/hr * x) + .210km Solving for x (time for car to catch up) we get .01 hours.
