Answer 1

The speed or rate is 6.322 miles/hour.

Explanation:

Given : Todd jogs 51 feet in 5.5 seconds.

To find : What is todds rate in miles per hour?

Solution :

The distance Todd jogs is 51 feet.

Convert feet into miles,

1 feet =
`(1)/(5280)` miles

51 feet =
`(51)/(5280)` miles

51 feet =0.0096590 miles

The time taken is 5.5 seconds.

Convert second into hour,

1 second =
`(1)/(3600)` hour

5.5 second =
`(5.5)/(3600)` hour

5.5 second =0.001527 hour

The speed formula is given by,

`\text{Speed}=\frac{\text{Distnace}}{\text{Time}}`

`\text{Speed}=(0.0096590)/(0.001527)`

`\text{Speed}=6.322`

Therefore, the speed or rate is 6.322 miles/hour.
