Nina ran 12 4/5 laps in 1/4 of an hour . At this rate , how many laps could she run in a hour ?

slega [8]

$\text{ Answer: There are }51 \frac{1}{5}\ laps.$

Explanation:

Since we have given that

Number of laps Nina ran is given by

$12\frac{4}{5}$

Time taken by Nina to ran the lap is given by

$\frac{1}{4}$

Now, we use the unitary method ,

$In\ \frac{1}{4}\ hour,\text{ Nina ran }12\frac{4}{5}=\frac{64}{5}\ laps\\\\In\ 1\ hour,\text{ Nina ran }\frac{\frac{64}{5}}{\frac{1}{4}}=\frac{256}{5}\ laps$

Now, we change it into mixed fraction,

$\frac{256}{5}=51\frac{1}{5}\ laps$

Hence,

$\text{ there are }51 \frac{1}{5}\ laps.$
