Answer 2

`\text{ Answer: There are }51 (1)/(5)\ laps.`

Step-by-step explanation:

Since we have given that

Number of laps Nina ran is given by

`12(4)/(5)`

Time taken by Nina to ran the lap is given by

`(1)/(4)`

Now, we use the unitary method ,

`In\ (1)/(4)\ hour,\text{ Nina ran }12(4)/(5)=(64)/(5)\ laps\\\\In\ 1\ hour,\text{ Nina ran }((64)/(5))/((1)/(4))=(256)/(5)\ laps`

Now, we change it into mixed fraction,

`(256)/(5)=51(1)/(5)\ laps`

Hence,

`\text{ there are }51 (1)/(5)\ laps.`
