If a turntable rotates through 720 degrees in one second, how many revolutions does it make in one minute.

120?

702-120=502

120 rotation in one minute.

To find out how many revolutions the turntable makes in one minute, we need to use the conversion factor between degrees and revolutions, as well as the given information.

First, let's break down the problem and set up the conversion:

Given: The turntable rotates through 720 degrees in one second.
To find: The number of revolutions the turntable makes in one minute.

Now let's go step by step:

1. Convert degrees to revolutions:
There are 360 degrees in one revolution since a full circle is divided into 360 degrees. Therefore, to convert degrees to revolutions, we divide the number of degrees by 360.
720 degrees ÷ 360 degrees/revolution = 2 revolutions

2. Convert seconds to minutes:
Since we know the turntable makes 2 revolutions in one second, we need to find out how many seconds are in one minute. There are 60 seconds in a minute, so we multiply the number of revolutions by the minutes:
2 revolutions × 60 minutes = 120 revolutions

Therefore, the turntable makes 120 revolutions in one minute, not 120.

If a clock turns 720 rotation in 1 second. How many rotation does it take place in 1 min
