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

`387\ \text{minutes}`

Explanation:

The time Gavin has is
`6(9)/(20)\ \text{hours}`

`6(9)/(20)=(20* 6+9)/(20)`

`=(129)/(20)\ \text{hours}`

`=6.45\ \text{hours}`

`=6* 60+0.45* 60=360+27`

`=387\ \text{minutes}`

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