Question

4) Twenty two feet per second is equal to how many miles per hour?

Answer 1

15mph

Explanation:

You need some conversion rates.

`(5)/(5)` is another name for one.
`(-2)/(-2)` is another name for one.
`(12 inches)/(1 foot)` is also another name for one. We are looking for units that mean the same thing as one to multiple with the units that we have to get the units that we want.

`(22feet)/(1 seocnd\\)` x
`(1 mile)/(5280 feet)` I can cross cancel no only numbers, but words. I can cross out the word feet and then multiple 22 x 1 and 1 x 5280 which would give me

`(22 miles)/(5280 seconds)` I can do the same thing to change seconds to hours. Here is how the whole thing could look:

`(22 feet)/(1 second)` x
`(1 mile)/(5280 feet)` x
`(60 seconds)/(1 minutes)` x
`(60 minutes)/(1 hour)` We can cross out the words: seconds, minutes, and feet. That leaves us with

`(22x60x60miles)/(5280 hours)` = 15 mph

Answer 2

Answer: 22 Feet per second is 15 mph

Explanation:

I divided 22 by 1.467 to get this answer.
