Question

A fan rotates at a speed of 123.5 rotations
per minute. If the speed of the regulator is adjusted to increase the speed of the fan 3.5 times, find the number of rotations per minute of the fan .
​

Answer 1

Answer:

The number of rotations per minute of the fan is 7.2 times.

Step-by-step explanation:

1 minute = 60 second

The fan rotates 3.5 times

Speed of fan rotation = 123.5

Speed of fan rotation in 3.5 times = 123.5 × 3.5

= 432.25

So in one minute fan rotate = 432.25 / 60

= 7.2 times
