Question

kelly is running a marathon that is 24 miles long. she has gone 4 miles in 32 minutes. how long will it take kelly to run the entire marathon? express your answer in hours

Answer 1

First we have to write down the informations we already have:

4miles......... 32minutes

24miles........ X (we write down x because we donť know)

Now we have to count.

X= 32: 4= 8

(One mile is 8minutes.)

X= 8x 24= 192

(We have to multiple it because we don't have only 1 mile.)

X= 192: 60= 3hours and 12 minutes

(We don't want it in minutes)

X= 3h 12min

Kelly' s run took 3hours and 12 minutes to run.

Answer 2

Answer: 3 hours and 12 minutes

Step-by-step explanation: First, you will divide 24 miles by 4 miles, and get 6 miles as your answer. Then, you will multiply the 32 minutes by the 6 and get 192 minutes. Next, you have to convert your minutes into hours. An hour is 60 minutes, so we will have to find how many times 60 goes into 192. When you divide 192 by 60 you get an answer of 3 and a remainder of 12. Finally you get an answer of 3 hours and 12 minutes.
