Q:
# Luis rides his bicycle 3/4 mile in 15 minutes, or 1/4 hour, along the bike trail. Assuming he rides at a constant rate, what is his speed, in miles per hour?

Accepted Solution

A:

Answer:His speed in miles per hour is:3MphStep-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.
