Question

Jenny walked 2.5 miles in 50 minutes . At this rate , how many minutes did it take her to walk 1 mile ?
A. 15
B. 20
C. 25
D. 30

Answer 1

For this question, let's use algebra!

2.5 miles  =  50 minutes
 1 mile             x minutes

x minutes = 50 x 1 ÷ 2.5
x minutes = 20

Hope this helps!

Answer 2

The answer is b. 

50 / 2.5= 20 (unit rate)

if Jenny walked 2.5 miles in 50 minutes, she walked 1 in 20 minutes becuase the unit rate is 20.

hopefully this helps
