The weight of one meter of rail is 32kg. How many railway cars with a carrying capacity of 60 tons

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

Let us denote the required number of cars by the symbol X.

X = (0.032 * 2 * 180,000) / 60; Where

0.032 is the mass of one meter of rail in tons;

2 – the number of rails in one railway track;

180,000 is the length of one rail in a track;

X = 11520/60 = 192.

Answer: You will need 192 cars with a carrying capacity of 60 tons.
