If a scow is towed at the rate of 3 miles an hour, how many hours will be needed to tow the scow 28 miles?

A10 hours, 30 minutes

B9 hours, 20 minutes

C12 hours

D9 hours, 15 minutes

I'd appreciate more than just the answer.. I'd appreciate if you explain it to me also in the simplest way you possible can.

I'm trying to score high on ASVAB.
