Answer 2

The correct conversion is
`93 \text{ mile per hour}= 136.4 \text{ feet per second}`

Explanation:

Given : Corey Kluber throws a 93 mile per hour fastball.

To find : How many feet per second does his fastball travel?

Solution :

Converting miles into feet,

`1 \text{ mile } = 5280 \text{ feet}`

`93 \text{ mile } = 5280* 93 \text{ feet}`

Converting hour into seconds,

`1 \text{ hour } = 60* 60 \text{ seconds}`

So,

`\frac{93 \text{ mile }}{1 \text{ hour }} = \frac{5280* 93 \text{ feet}}{60* 60 \text{ seconds}}`

`93 \text{ mile per hour}= 136.4 \text{ feet per second}`

Therefore, The correct conversion is
`93 \text{ mile per hour}= 136.4 \text{ feet per second}`
