The track members were required to complete 40 pushups in 5 minutes. Write the rate in 3 different ways.

a. 0.133 pushups/s b. 8 pushups/s c. 1200 pushups/s

Step-by-step explanation:

To write the rate in 3 different ways, we have to use seconds, minutes and hours respectively for the time.

So, a. Number of pushups per second

rate, R₁ = number of pushups per second

= number of pushups/ total time in seconds

= 40 pushups/(5 × 60) s

= 40 pushups/300 s

= 0.133 pushups/s

b. Number of pushups per minute

rate, R₂ = number of pushups per minute

= number of pushups/ total time in minutes

= 40 pushups/5 min

= 8 pushups/s  

c. Number of pushups per hour

rate, R₃ = number of pushups per hour

= number of pushups/ total time in seconds

= 40 pushups/(5 ÷ 60) s

= 40 pushups/(1/30) h

= 40 × 30 pushups/s

= 1200 pushups/s
