A car travels 132 miles on 4 gallons of gas. At the same rate, how many gallons of gas are needed to travel 231 miles
To find out how many gallons of gas are needed to travel 231 miles at the same rate, we can set up a proportion based on the information given:
132 miles / 4 gallons = 231 miles / x gallons
Cross multiply to solve for x:
132 * x = 4 * 231
132x = 924
x = 924 / 132
x = 7
So, 7 gallons of gas are needed to travel 231 miles at the same rate.
