Question

Paul's family drove 377 mi to the beach averaging 58 ​ mi/h ​ on the way there. On the return trip home, they averaged 65 ​ mi/h ​ .
What was the total time Paul's family spent driving to and from the beach?

11.3 h

11.6 h

12.3 h

13 h

Answer 1

The answer is 12.3 hours.

On the way to the beach, the family averaged 58 mi/h over 377 mi, so we take 377/58 to find the amount of time spent going to the beach. 377/58 = 6.5 hours.

On the way back, they averaged 65 mi/h over the same 377 mi, so we take 377/65. 377/65 = 5.8 hours.

6.5 + 5.8 = 12.3
