Answer:
80 minutes
Step-by-step explanation:
As we don't know the whole quantity, we will take the whole quantity as 'x'.
60% of whole quantity = 48 minutes
60% of x = 48
[tex]\sf \dfrac{60}{100}*x = 48 \\\\\text{Multiply the entire equation with the reciprocal of $\dfrac{60}{100}$}\\\\Reciprocal \ of \ \dfrac{60}{100}=\dfrac{100}{60}\\\\\\x = 48 * \dfrac{100}{60}[/tex]
x = 8 * 10
x = 80 minutes
x = 1 hour 20 minutes
