Question

Find the value of following :
$15\%$ of $2$ minutes

Answer 1

Given,
$15\%$ of $2$ minute.
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.
