# 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?

750 minutes

Explanation

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
$$500 \div 40=t$$
12.5 = t
It takes Rachel 12.5 hours to make the round-trip drive. Multiply by 60 to find the answer in minute
$$12.5 \times 60=750 \text { minutes }$$
