Question

A jogging track is 1/4 mile. Sara ran 14 laps.

How many more laps does she need to run
to reach 5 miles?

Answer 1

Sarah need to run
`1(1)/(2)` more miles.

Explanation:

In order to tell how much more she needs to run we need to find out how much she ran so far. Since we know that one lap is
`(1)/(4)` of a mile, and that she ran 14 laps we can easily find out how much she ran so far by multiplying
`(1)/(4)` by 14. And so we get......

`((1)/(4) )(14) = (14)/(4) = 3(2)/(4) = 3(1)/(2)`

Now that we know how much she ran so far (
`3(1)/(2)` miles), in order to find out how much more she has to run we just have to substract the distance she ran so far from the total distance she wants to reach (in our case 5 miles) . After doing this we get the answer which is......

`5 - 3(1)/(2) = (5)/(1) - (7)/(2) = (10)/(2) - (7)/(2) = (3)/(2) = 1(1)/(2)`

Answer 2

6 more laps
