Question

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 14 days without the warning light coming on? Explain your reasoning.

Answer 1

2

Explanation:

Answer 2

20 days

Explanation:

Subtract 1.5 gallons from 14 gallons to obtain the number of days the car will run without the warning light going on: 12.5 gallons.

Dividing this result by 0.6 gallons/day, we get

12.5 gal

------------------- = 20.82 days. Round this down to 20 days. (We're not

0.6 gal/day dealing in partial days.)
