Solution

Step : Finding $15 % of 2 minutes$
Given, $15 % of 2 minutes$ .
We know that, $1 min = 60 sec.$
So, $2 min = 120 sec$
$15 % of 2 minutes = 15% of 120 sec$
$= \frac{15}{100} \times 120$
$= 15 \times \frac{12}{10}$
$= \frac{180}{10}$
$18 sec = 0.3 min$
Hence, $15 % of 2 min is 0.3 min or 18 sec.$
