Cheyenne ran a 5.6-kilometer race in 40 minutes. What was her speed in kilometers per hour? A. 224 B. 8.4 C. 7.1 D. 0.14

xz_007 [3.2K]

Hey there! :D

Let's find what Cheyenne runs in 10 minutes.

Divide 5.6 by 4.

5.6/4= 1.4

Multiply that by 6. (there are 60 minutes in an hour)

1.4*6= 8.4

"B" is the answer.

I hope this helps!
