For every 140 feet that Kelly rides on her bicycle, the wheels turn 20 times. About

how many times do the wheels turn in 5 miles? (1 mile = 5,280 feet)

Respuesta :

Answer : The number of times the wheels turn in 5 miles is, 3774

Step-by-step explanation :

First we have to convert 140 feet in to miles.

Conversion used :

1 mile = 5,280 feet

or,

5,280 feet = 1 mile

So, 140 feet = [tex]\frac{140}{5280}=0.0265[/tex] mile

Now we have to calculate the number of times do the wheels turn in 5 miles.

As, the number of times wheel turn in 0.0265 mile = 20 times

So, the number of times wheel turn in 5 mile = [tex]\frac{5}{0.0265}\times 20=3774[/tex] times

Therefore, the number of times the wheels turn in 5 miles is, 3774
