Question

A fan does 65 rotations in 52 seconds how long does it take to do 200 rotations

Answer 1

160 seconds

Explanation:

We have 65 rotations in 52 seconds, let's represent it like this:

`(52 seconds)/(65 rotations)`

Now, let's multiply this by 200 rotations, and cancel out the rotations on the bottom:

`(52 seconds)/(65 rotations) * 200 rotations`

See how there is rotations on both the top and bottom? This cancels both of them and leaves seconds!

Multiply the above equation and we get:

160 seconds or 2 minutes 40 seconds.

Hope this helps! Good luck and if you have questions please leave them in the comments!

Answer 2

Answer: 160 seconds

Explanation:

First let us find the number of seconds per rotation

52 second/65 rotations

52/65

0.8 seconds/1 rotation

0.8 seconds per rotation

Now let us multiply 0.8 by 200 to get our answer

0.8 * 200

160

It takes 160 seconds to do 200 rotations
