Question
Find 2% of 2 hours 30 min
✓
Answer
$2 \%$ of 2 hours $30 \mathrm{~min}$
$\because 1$ hour $=60$ minutes
$\therefore 2$ hours 30 min. $=2 \times 60 \mathrm{~min} .+30 \mathrm{~min}$.
$=120+30=150 \mathrm{~min}$.
$=150 \times \frac{2}{100}=\frac{30}{10}$
$=3$ minutes
$\because 1$ hour $=60$ minutes
$\therefore 2$ hours 30 min. $=2 \times 60 \mathrm{~min} .+30 \mathrm{~min}$.
$=120+30=150 \mathrm{~min}$.
$=150 \times \frac{2}{100}=\frac{30}{10}$
$=3$ minutes
