Question

Jamie and frank went to the neighborhood pool for two hours they swam in the pool for forty-five minutes played on the water slides for 35 minutes and played sand volleyball for the rest of the time what percent of the time did they play sand volleyball A. 40% B. 33 1/3% C. 30% D. 66 2/3%

Answer 1

B. 33 1/3%

Explanation:

The total time, they played in the pool,

t = 2 hours =2x60= 120 minutes.

The time in which, they swam in the pool,
`t_1 =45` minutes.

The time in which, they played on the water slides,
`t_2 =35` minutes.

They played sand volleyball for the rest of the time.

Let
`t_3` be the time in which, they played sand volleyball.

So, the total time=
`t_1+t_2+t_3 = t`

Using the given values, we have

`45+35 +t_3=120`

`\Rightarrow t_3=120-80=40` minutes

The percentage of time for which they played volleyball

`=(t_3)/(t)* 100`

`=(40)/(120)* 100`

`=33(1)/(3) \%`

Hence, option (B) is correct.
