Problema Solution
The scoop of an excavator holds 27 ft3 of sand. If the capacity of a freight car is 40 tons of sand and we know that 1 ft3 of sand weighs 0.5 tons, how many freight cars can be filled with 120 loads?
Answer provided by our tutors
120 loads has a weight of 120*27*0.5 = 1620 tons
1620 : 40 = 40.5 freight
We conclude that 41 freight cars can be filled with 120 loads.
