Question

80 min = ___ hr.

• A. $\frac{4}{3}$
• B. $\frac{3}{4}$
• C. $\frac{6}{5}$
• D. $\frac{2}{3}$

Answer 1

The correct option is A $\frac{4}{3}$

60 min = 1 hr
then, 1 min = $\left(\frac{1}{60}\right)$ hr
or, 80 min = $\left(\frac{1}{60}\right)\times 80$ hr
$=\frac{80}{60}$ hr
$=\frac{4}{3}$ hr
