Question

It took Sandy two hours to jog 13 miles. She ran 7 1/2 miles in the first hour. How far did she run during two hours the second hour?

Answer 1

`5 1/2" miles"`

Explanation:

`"require to calculate"`

`13-7 1/2larr" gives distance remaining"`

`"note that "7 1/2=7+1/2`

`rArr13-(7+1/2)`

`=13-7-1/2`

`=6-1/2`

`=5 1/2" miles"larr" in the second hour"`

Answer 2

She ran `5 1/2` miles the second hour.

Explanation:

`13` miles - `7 1/2` miles `= 5 1/2` miles.

I assumed the question should be:
`"How far did she run during "cancel("two hours")"the second hour?"`
