There are trucks and cars traveling in a single lane. The size of Truck is 10 m while a size of a car is 5 m. There should be 20 m gaps between each truck and 15 m gap in each car. Cars and Trucks can travel alternately at the speed of 36 km/h. How many vehicles can cross a bridge (nothing particular value given about to the bridge) in an hour?
total length(cars and trucks and gaps) - 5 + 15 + 10 + 20 = 50
36000/50 = 720 car and trucks = 1440 vehicles(I marked it as 720!!)
