Question

Rafiq exercised for $\frac{3}{6}$ of an hour, while Rohit exercised for $\frac{3}{4}$ of an hour. Who exercised for a longer time?

Answer 1

We know that

$1\mathrm{hr}=60\min$

Now given that

Rafiq's exercise time $=\frac{3}{6}$ of an hour $=\frac{3}{6}\times 60\min =\frac{3\times 60}{6}\min =30\min$

Rohit's exercise time $=\frac{3}{4}$ of an hour $=\frac{3}{4}\times 60\min =\frac{3\times 60}{4}\min =45\min$

As

$45\min >30\min$

Hence Rohit exercised for a longer time than Rafiq.
