Question

Fanuela walked for 3.9 miles per hour for 0.72 hours. How far did she walk?

Answer 1

speed = distance/time
3.9=d/0.72
d= 3.9 x 0.72
d= 2.808 miles

Answer 2

Answer: Fanuela walked 2.808 miles.

Explanation:

If 3.9 = 100 and we need to work out what 72 is we can do this/

3.9 ÷ 10 = 0.39 which = 10

0.39 ÷ 10 = 0.039 which = 1

so with these calculations we can solve the problem.

To get the 70 in 72 we can do 0.39 x 7 (10 x 7) which = 2.73.

To get the remaining 2 in 72 we can do 0.039 x 2 (1 x 2) which = 0.078.

2.73 + 0.078 = 2.808.

Fanuela walked 2.808 miles.
