Given:

Hayden
1(1)/(2) minutes to complete each level of his video game.

He plays for
10(1)/(4) minutes.

To find:

The number of levels he will complete.

Solution:

We have,

Required time for each level =
1(1)/(2)

Total time =
10(1)/(4)

The number of level is


n=\frac{\text{Total time}}{\text{Required time for each level}}


n=(10(1)/(4))/(1(1)/(2))


n=((10(4)+1)/(4))/((1(2)+1)/(2))


n=((41)/(4))/((3)/(2))

On further simplification, we get


n=(41)/(4)* (2)/(3)


n=(41)/(6)


n=6.8333...

Number of levels must be a whole number. So, approx to value to the preceding whole number.


n\approx 6

Therefore, Hayden will complete 6 levels if he plays for
10(1)/(4) minutes.
