Every day, Bert spends an hour commuting to and from his office, driving at an average speed of 50 mph and taking the same route each way. How far does Bert live from his office?

A 25 miles
Explaination
Use the distance formula, where d stands for distance, r stands for the (constant or average) rate of speed, and t stands for time. Remember that his total commute is 1 hour, so one-way, it will be 0.5 hours. d=rt
d = 50(0.5)
d = 25.
B 50 miles
C 30 miles
D 15 miles
