Answer:
[tex]\frac{1}{7}\,\,miles/minute[/tex]
Step-by-step explanation:
Given: Travis and Tony took 40 minutes to skate 5 miles and the return trip took them 30 minutes
To find: average speed for the trip
Solution:
Total distance = 5 + 5 = 10 miles
Total time = 40 + 30 = 70 minutes
So,
Average speed for the trip = Total distance/Total time = [tex]\frac{10}{70}=\frac{1}{7}[/tex] miles/minute
