Answer:
[tex]12,600\ ft[/tex]
Step-by-step explanation:
step 1
Find out the number of revolutions in one hour
we know that
The bicycle wheels are making 30 revolutions per minute
One hour are 60 minutes
so
using proportion
[tex]\frac{30}{1}\ \frac{rev}{min}=\frac{x}{60}\ \frac{rev}{min}\\\\x=60(30)\\\\x=1,800\ rev[/tex]
step 2
Find out how many feet the bicycle will travel in one hour
we know that
A bicycle moves approximately 7 feet with each revolution and the number of revolutions in one hour is 1,800
so
Multiply the number of revolutions in one hour (1,800 rev) by 7 feet
[tex](1,800)7=12,600\ ft[/tex]
