Jill's car tires are spinning at a rate or 120 revolution per minute. If her car tires' radii are each 14 inches, how far does she travel in 5 minutes?
Circumference = pi * diameter
C = 3.14 * 28
C = 87.92
120 * 87.92 = 10 550.4 inches per minute
5 * 10,550.4 = ? inches in 5 minutes
To find out how far Jill travels in 5 minutes, we need to calculate the distance covered by her car tires in one revolution and then multiply that by the number of revolutions in 5 minutes.
First, let's calculate the circumference of the car tire. The circumference is equal to the distance traveled in one revolution.
The formula for the circumference of a circle is:
Circumference = 2 * π * radius
Given that the radius of Jill's car tire is 14 inches, we can substitute that into the formula:
Circumference = 2 * π * 14 inches
Now, we can calculate the distance covered by Jill's car tires in one revolution.
Next, we need to calculate the number of revolutions in 5 minutes. We are given that the car tires are spinning at a rate of 120 revolutions per minute. So, in 5 minutes, the car tires would complete:
Number of Revolutions = 120 revolutions/minute * 5 minutes
Finally, we can multiply the distance covered in one revolution by the number of revolutions in 5 minutes to find out how far Jill travels:
Distance Traveled = Circumference * Number of Revolutions
Let's plug in the values and calculate:
Circumference = 2 * π * 14 inches
Number of Revolutions = 120 revolutions/minute * 5 minutes
Distance Traveled = Circumference * Number of Revolutions
After substituting the values, you can calculate the distance traveled by Jill in 5 minutes.
