Question

Suzzy walks ¾ mile around the high school track in ½ hour. How far can she walk in 2 hours?

Answer 1

3 mi.

Explanation:

Hullo! :D

Let's take a more slow way of solving this:

If Suzzy walks 3/4 mile in 1/2 hour, she will walk 3/4 × 2 miles in 1 hour. (because 1/2 × 2 = 1)

`(3)/(4)` × 2 =
`(6)/(4)` =
`(3)/(2)`

So Suzzy is walking at a rate of
`(3)/(2)` per hour.

Therefore, to find two hours, all we do is multiply
`(3)/(2)` by 2.

`(3)/(2)` × 2 = 3.

So Suzzy can walk 3 miles in two hours.

Answer 2

Explanation:

3/4 + 3/4 = 6/4 = 1 1/2= 1.5 (this is one hour)

1.5 x 2 = 3

she can walk 3 miles in 2 hours.
