Question:
Rachel is driving to visit her mother, who lives 250 miles away. How long will the drive be, round-trip, if Rachel drives at an average speed of 40 mph?
A
750 minutes
Explaination
The distance from Rachel’s house to her mother’s house is 250 miles, so round-trip, the distance is 500 miles. Plug this into the distance formula:
d = rt
500 = 40t
500 ÷ 40 = t
12.5 = t
It takes Rachel 12.5 hours to make the round-trip drive. Multiply by 60 to find the answer in minute
12.5 × 60 = 750 minutes.
