If beth can walk two and a half miles in 28 minutes, how many minutes will it take her to walk 10 miles ?

Beth can walk 2 1/2 miles in 28 minutes

Multiply both by 2

2 1/2 x 2= 5

28 x 2 = 56

Beth can walk 5 miles in 56 minutes

Next, multiply both by 2 again

5 x 2 = 10

56 x 2 = 112

Beth takes 112 minutes to walk 10 miles

hope this helps
