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
