Answer:


396 ft/min faster

Answer:

396 feet per minute

Step-by-step explanation:

Hello

I think I can help you with this

to find the difference of speed in feet per minute , we can find the difference and then convert  miles per hour into feet per minute,also the equivalences must be known,in this case

1 mile = 5280 feet

1 hour = 60 minutes

Step 1

find the difference

Yuzo's speed=27 mph

jermaine's speed=22.5

difference=27 mph-22.5 mph=4.5 mph

Step 2

convert 4.5 mph into feet per minute

to do this, use mph as a fraction and multiply by a fractional with the equivalence in such a way that the units are canceled

[tex]\frac{1 hour}{60 min}=1\\\\\frac{5280 feet}{1 mile}=1\\\\\\[/tex]

you are multiplying by one, you are not changing the quantity only the unit of measure

[tex]4.5 \frac{miles}{hour}*(\frac{1 hour}{60 min} )*(\frac{5280 feet}{1 mile})\\\frac{4.5*1*5280\ miles\ hour\ feet}{1*60*1\ hour\ min\ mile} \\396 \frac{feet}{min}[/tex]

Have a great day
