Question

if a turntable rotates through 720degrees in one second, how many rotations does it make in one minute?

Answer 1

everything will be ok

hope u will not rotate it once again

Answer 2

Turntable makes 120 rotations.

Given - Degree of rotation in 1 second

Find - Number of rotations in 1 minute

Solution - As per the known facts -

• 1 minute = 60 seconds
• 1 rotation = 360°

Usign these information to find number of rotations by turntable in 1 minute.

Number of rotations in 1 second = 720÷360

Performing multiplication to find the number of rotations

Number of rotations in 1 second = 2

Number of rotations in 1 minute = 2×60

Performing multiplication to find the number of rotations

Number of rotations in 1 minute = 120

Hence, turntable rotates 120 times in 1 minute.
