The mass of one meter of rail is 32 kg. How many railway cars with a carrying capacity of 60 tons will be needed to transport all the rails necessary for the construction of a single-track railway 180 km long?

Answer: 192 wagons are required.

A single-track railway is a track with two rails. This means that to build a road 180 km long, you will need rails:

180 * 2 = 360 km.

One kilometer contains 1000 meters.

Means:

360 km = 360 * 1000 = 360,000 m.

We multiply the mass of one meter of rail by the number of meters of rails and we get the mass of the rails used for construction.

32 * 360000 = 11520000 kg.

One ton contains 1000 kg. I.e:

11520000 kg = 11520 t.

We divide the resulting value by the carrying capacity of a carriage of 60 tons and we obtain the number of cars required for the transportation of rails:

11520/60 = 192 wagons
