Question

During the first leg of a backpacking trip, a group of hikers covered 10.4 miles in 3 hours and 1 minute. The next day, the group hiked 8.6 miles in 3 hours and 47 minutes. What was the group's average speed over the two days? Answer as a decimal rounded to the nearest tenth.

Answer 1

2.79 mi/hr ( for the time they were actually moving)

Explanation:

average speed = total distance / total time

= ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr
