Answer:

His speed in miles per hour is:

3Mph

Step-by-step explanation:

Depending on the speed you take in miles per minute when passing it to miles per hour, you should consider the time it takes you to travel a mile.

Now: If 3/4 of a mile is 0.75 miles.

And it takes 15 minutes, so how long does it take 1 mile?

It is a rule of three.

0.75 miles = 15 minutes

1 mile = X

Clearing X would give :

 X = 15 * 1 / 0.75

X = 20 minutes takes a mile to travel

Now if it goes to 1Mpm how much is in Mph?

If it takes 20 minutes to travel 1 mile, how many travels in 60 minutes (1 hour)

Again rule of 3.

20 minutes = 1 mile

60 minutes = X

Clearing X would give:

X = 60/20

X = 3 miles per hour.

Luis rides 3 miles per hour.

Luis speed in miles per hour is 3

Luis' speed in miles per hour can be determined by dividing the distance he rode in miles by the time in hours. The time measurement that would be used would be  in hours instead of minutes because the measurement has to be in miles per hour

Speed = distance / time

Distance = [tex]\frac{3}{4}[/tex]

Time = [tex]\frac{1}{4}[/tex]

Speed =  [tex]\frac{3}{4}[/tex] ÷  [tex]\frac{1}{4}[/tex]

[tex]\frac{3}{4}[/tex] x 4 = 3 miles per hour

In order to determine Luis' speed, divide the distance he rides by the time.
