if I were traveling 15 miles at 13 miles per hour how long will it take.
Clearly it will take a little more than an hour since you only go 13 miles in an hour.
Going at 13 miles per hour it takes you 1/13th of a an hour to travel 1 mile. At this rate it takes 1/13 x 15 hours to go 15 miles. 1/13 x 15 = 1.15 or 1 hour and 9 minutes.Cheers,
