Answer 2

His sister takes 20 minutes or $\frac{1}{3} \: hours$ more time than his brother in completing English homework.

Given:-

Danish complete English homework in 5 by 12 hours

His sister complete English homework in 3 by 4 hours

To Find:- Who takes more time to complete the work and how much

Solution:-

Danish complete English homework in hours = $\frac{5}{12}$

As we know 1 hour = 60 mins

Danish complete English homework in minutes=

$\frac{5}{12} \times 60 \\ = 25$

= 25 minutes

His sister complete English homework in hours =

$\frac{3}{4}$

His sister complete English homework in minutes=

$\frac{3}{4} \times 60 \\ = 45$

= 45 minutes

His sister takes more time in completing English homework =

$45 - 25 = 20 \: minutes\\ = \frac{20}{60} \: hours \\ = \frac{1}{3} \: hours$

Hence, His sister takes 20 minutes or $\frac{1}{3} \: hours$ more time than his brother in completing English homework.
