Problema Solution
if 68 t of rail is needed for 1 km of track, how many tonnes will be required for 762 km, and what will be its cost at $1,425 per tonne ?
Answer provided by our tutors
First, lets determine how many tons will be needed. We are given the conversion factor 68 t/km. Therefore, for 762km, the following is needed:
762km (68 t/km)=51,816 tons
Now, lets determine the cost by using the conversion factor $1,425/ton:
51,816 tons ($1,425/ton)= $73,837,800
