A motor makes 5256.75 complete rotations in 4.89 minutes. How would you calculate the number of degrees the motor rotates in 21.6 seconds?
1 Answer
See a solution process below:
Explanation:
First, we can write the expression in the problem as:
Next, we can convert rotations to degrees. 1 rotation is equation to
Then we can convert minutes to seconds. 1 minute is 60 seconds. We can again multiply the fraction by 1 to convert to degrees without changing the value of the fraction:
To find the number of degree the motor rotates in 21.6 seconds we can yet again multiply our fraction by the appropriate form of
The motor rotates 139,320 degrees in 21.6 seconds.
