A wheel truns through 90 revolutions per minute. How many degrees does it turn through in 1 second?
1 rotation = 360 degrees
90 rotations = 90 x 360 =32400
1 min = 60 seconds
therefore = 32400/60= 540 degrees/sec
therefore the answer = 540 degrees/sec
1revolution = 360 degrees
90 revolutions = 90*360 degrees
1 minute = 60 seconds
Therefore wheel turns through 90*360/60 → 540 degrees per second
