A supply officer needs to order fuel for a fleet of 15 vehicles. Each vehicle holds 20 gallons of fuel, and the officer wants to have enough fuel for 3 full refills for each vehicle. How many gallons of fuel must be ordered?
- A600 gallons
- B1200 gallons
- C900 gallons
- D300 gallons
Show answer & explanationAnswer & explanation
Correct answer: C. 900 gallons
First, calculate the total fuel needed for one refill for the entire fleet: 15 vehicles * 20 gallons/vehicle = 300 gallons. Then, multiply this by the number of refills: 300 gallons * 3 refills = 900 gallons.
Why the other options are wrong
- A. Incorrect multiplication, possibly for 2 refills.
- B. Incorrect multiplication, possibly for 4 refills.
- D. This is enough fuel for only one refill for the entire fleet.
