Question

Caroline drove 350 miles to her grandmothers house. the trip took her 5 1/4 hours. what was her average speed in miles per hour

Answer 1

350/5 1/4= 66.6666666667 miles per hour

Answer 2

Answer:

Caroline’s average speed (in mph) is 66 2/3 mph

Step-by-step explanation:

Speed x time = distance

Caroline’s speed is unknown, so we can call that x. The distance she drove was 350 miles, and the time it took her was 5 1/4 hours.

X • 5 1/4 = 350

350 divided by 5 1/4 = 66 2/3

X = 66 2/3
