Question

A cowboy rode his horse 45 miles at 15 and then rode another 35 miles at 10 . How long did the ride last? A. 6 h B. 6.5 h C. 60 h D. 65 h

Answer 1

You are given the distance of the horse of 45 miles at 15miles per hour and another 35 miles at 10 miles per hour. You are asked the total time in hours of the cowboy riding his horse. You have to get the time each mile the cowboy rode.  

45 miles/15 miles per hour = 3 hours
35 miles/10 miles per hour = 3.5 hours
3 hours + 3.5 hours = 6.5 hours
So the answer is B. 6.5 hours.

Answer 2

The ride total lasted 6.5 hours
45/15=3
35/10=3.5
3+3.5=6.5
