Question:
Solution:
Consider the following diagram ("rule of 3"):
by cross-multiplication we get:
[tex]\text{? gallons = }\frac{370\text{ miles x 1 gallon}}{32\text{ miles}}\text{ = 11.56 gallons}[/tex]
Thus the car must use 11.56 gallons if he wants to travel 370 miles. Notice that the car has 12 gallons, so we can conclude that the car can travel the 370 miles because it has enough gallons.
