The mass of one meter of a rail is 32 kg. How many wagons of 60 tons are needed to transport a rail for 180 km.

Let’s determine how many kilograms the volume of rails for 180 kilometers will equal, knowing that one meter of rail weighs 32 kilograms, and also that one kilometer, by definition, contains 1000 meters:

2 * 80 * 1000 * 32 = 11520000.

Let us determine how many cars will be needed to transport the found volume of rails, knowing by the condition of the problem that the carrying capacity of one such car is 60 tons:

11520000: (60 * 1000) = 192.

Answer: 192 wagons are required for transportation.
