To calculate how many revolutions a park ride will make in 2 minutes, first convert 180 seconds into minutes. Since 60 second is 1 minute, 180 can be expressed as;
> 180 seconds * 1 minute/ 60 seconds
> 180 * 1 minute/ 60
> 180 minute/ 60
> 3 minutes
Since the park ride will make 156 revolution in 180 seconds or 3 minutes, divide 156 revolution by 3 minutes to solve for revolution/minute.
> 156 revolution / 3 minutes
> 156 revolution / 3 minutes
> 52 revolution/ minute.
Since we are looking for how many revolutions the park ride in 2 minutes, multiply the rate 52 revolution/ minute by 2 minutes to get the number of revolution.
> 52 revolution/ minute * 2 minutes
> 52 revolution * 2
> 104 revolution.
The park ride will make 104 revolutions in 2 minutes.
