Answer 6

We have to divide, but currently we have too many variables. We have hours, minutes, and miles, when they're asking, "how many minutes did it take her to run 1 mile"

Answer 7

im still confused

Answer 8

we have two different determiners of time in the numerator, hours and minutes, when they are just asking for minutes.

Answer 9

so 28 minutes?

Answer 10

Well it took her 3hrs and 28 minutes to do the 26 miles, but we want the total time it took her to do those 26 miles, in minutes.

Answer 11

Convert 3hrs to minutes, then add the 28 minutes, then divide the total minutes it took her to do the run by 26 miles, giving you the rate.

Answer 12

so 8 minutes?
