The mass of one meter of rail is 32 kg. How much is needed for railway cars with a carrying capacity of 60 tons to move all the rails necessary for the construction of a single-track railway with a length of 180 km.
32 kg – weight of 1 meter of rail.
60 t is the carrying capacity of the 1st railway carriage.
180 km is the length of a single-track railway.
180 km * 2 = 360 km.
Because Since the rails are double-sided, the length of the single-track railway will be 360 km.
360 kilometers * 1000 meters = 360,000 meters.
360,000 m * 32 kg = 11,520,000 kg.
11 520 000 kilograms * 0.001 tons = 11 520 tons will need rails.
11 520/60 = 192.
192 railway cars will be needed to transport rails.
Solution: 192 wagons.
