Question

If Gavin has 6 9/20th of time left to play videos, what is that mixed number written in minutes and seconds?

Answer 1

Answer:

$387\ \text{minutes}$

Step-by-step explanation:

The time Gavin has is $6\dfrac{9}{20}\ \text{hours}$

$6\dfrac{9}{20}=\dfrac{20\times 6+9}{20}$

$=\dfrac{129}{20}\ \text{hours}$

$=6.45\ \text{hours}$

$=6\times 60+0.45\times 60=360+27$

$=387\ \text{minutes}$

The number of minutes is $387\ \text{minutes}$.
