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
Mars2501 [29]

Answer: The wheels turn about 3771 times in 5 miles.

Step-by-step explanation:

Given, Kelly rides on her bicycle such that the number of times wheels turn for every 140 feet = 20

Turns for every feet = \dfrac{20}{140}=\dfrac{1}{7} ...(i)

To find : Number of times wheels turn in 5 miles.

Since , 1 mile = 5,280 feet

Then, 5 miles = 5 x (5,280 feet) = 26,400 feet

Now , Number of times the wheels turn in 26,400 feet = 26400 x (Turns for every feet)

26400\times\dfrac{1}{7}=3771.42857143\approx3771   [From (i)

Hence, the wheels turn about 3771 times in 5 miles.

a scale factor applies normally to lengths (one-dimensional sizes).

and the perimeter is calculated just by lengths (the side lengths).

so, we can apply the scaling factor directly to the perimeter.

perimeter of DEF = 5/2 × perimeter of ABC = 5/2 × 65.5 =

= 163.75 ft
