Question

A small rocket fuel processing plant was built in order to provide the fuel for a special asteroid mining mission. The plant can produce 15 gallons of fuel per hour, and has 75 days until the mission. If the mission will require 7875 gallons of rocket fuel, how many hours a day will the plant need to be open in order for the mission to launch?

Answer 1

The plant needs 525 hours (7875 / 15) to produce the fuel.

525 / 75 = 7

The plant needs to be producing 7 hours a day for 75 days.
