Answer:

1.75 ton·miles = 18,480,000 ft·lb

Explanation:

You want to know the work done by a freight train locomotive as it pulls cars with a force of 7 tons over a distance of 1/4 mile.

Work is the product of force and distance:

W = Fd

W = (7 t)(1/4 mi) = 7/4 t·mi

In foot·pounds, this is ...

1.75 t·m × 2000 lb/t × 5280 ft/mi = 18,480,000 ft·lb
