A truck covers 376 km at a certain speed in 8 hours. How
much time would a car take at an average speed of 13 km/h more than that of the speed of the truck to cover a distance that is 44 km more than that traveled by truck?Solution
Speed of the truck = (376/8) = 47 km/h Average speed of car = 47 + 13 = 60 km/h Distance to be covered by the car = 376 + 44 =420 km required speed = 420/60 = 7 km/h
