If a Ferris wheel takes 45 seconds to make a complete rotation, how many rotations will it complete in 3 hours?
First: Multiply 3 * 60 * 60 to find the number of seconds in 3 hours.
Next: Divide the number of seconds in 3 hours by 45.
To find out how many rotations the Ferris wheel will complete in 3 hours, we need to convert the time to seconds and then divide by the time it takes for one rotation.
First, let's convert 3 hours into seconds. There are 60 minutes in an hour and 60 seconds in a minute, so:
3 hours = 3 * 60 * 60 = 10,800 seconds
Now, we can calculate the number of rotations by dividing the total time in seconds by the time taken for one rotation:
Number of rotations = Total time (in seconds) / Time taken per rotation
Number of rotations = 10,800 seconds / 45 seconds
Simplifying this, we get:
Number of rotations = 240 rotations
Therefore, the Ferris wheel will complete 240 rotations in 3 hours.
To find out how many rotations the Ferris wheel will complete in 3 hours, we need to convert the given time to seconds and then divide it by the time it takes to complete one rotation.
First, let's convert 3 hours to seconds. Since there are 60 minutes in an hour and 60 seconds in a minute, we can multiply 3 hours by 60 and then by 60 again to get the total number of seconds:
3 hours * 60 minutes/hour * 60 seconds/minute = 10,800 seconds.
Now, let's divide the total number of seconds by the time it takes to complete one rotation (45 seconds) to find the number of rotations:
10,800 seconds / 45 seconds/rotation = 240 rotations.
Therefore, the Ferris wheel will complete 240 rotations in 3 hours.
