A car is moving at a rate of 60 miles per hour. the diameter of the wheels are 2.6 ft.
how do you find the revolutions per minute that the wheels are rotating?
The car travels one mile in one minute.
C = pi * d
C = 3.14 * 2.6
C = 8.164 feet
5,280 / 8.164 = 646.74 revolutions per minute
thank you!
You're welcome.
To find the revolutions per minute (RPM) that the wheels are rotating, you need to know the speed of the car, the diameter of the wheels, and apply a few formulas.
Step 1: Convert the speed from miles per hour to feet per minute.
Since there are 5,280 feet in one mile and 60 minutes in one hour, you can multiply the car's speed (60 miles/hour) by both conversion factors to obtain the speed in feet per minute. Calculation: 60 miles/hour * 5,280 feet/mile * (1 hour/60 minutes) = 5,280 feet/minute.
Step 2: Calculate the circumference of the wheels.
The circumference of a circle is found by multiplying its diameter by π (pi). Given that the diameter of the wheels is 2.6 feet, the circumference can be calculated as follows: Circumference = π * diameter = 3.14 * 2.6 feet.
Step 3: Divide the speed in feet per minute by the circumference of the wheels to find the RPM.
To determine how many wheel revolutions occur in one minute, divide the speed in feet per minute (5,280 feet/minute) by the circumference of the wheels (3.14 * 2.6 feet). Calculation: 5,280 feet/minute / (3.14 * 2.6 feet/wheel) = X revolutions/wheel/minute.
Therefore, if you follow these steps, you will be able to calculate the revolutions per minute (RPM) that the wheels are rotating.
