Question

Pat bounces a basketball 23 times in 30 seconds. At that rate, approximately how manytimes will Pat bounce the ball in 150 seconds?

Answer 1

Given: That Pat bounces a basketball 23 times in 30 seconds

To Determine: The rate of bouncing for 150 seconds

Solution

`rate=\frac{number\text{ of bpunces}}{number\text{ of seconds}}`

Let the number of bounces for 150 seconds be x, therefore comparing the rate would give

`(23)/(30)=(x)/(150)`

Cross multiply

`30x=23*150`

Divide both sides by 30

`\begin{gathered} (30x)/(30)=(23*150)/(30) \\ x=23*5 \\ x=115 \\ x\approx120 \end{gathered}`

Hence, the approximate rate
