Mrs. Ebert is driving to Ohio to visit family. If her truck can drive 552 miles on 23 gallons of gas, how many gallons of gas would she need if the total trip was 840 miles?
We can set up a proportion to solve this problem. Let "x" represent the number of gallons needed for the total trip.
552/23 = 840/x
Cross multiplying, we get:
552x = 840 * 23
Dividing both sides by 552, we find:
x = (840 * 23)/552
After evaluating the right side of the equation, we get:
x ≈ 35
Therefore, Mrs. Ebert would need approximately 35 gallons of gas for the total trip.
