What is the tangential velocity of a record player which makes 11 revolutions in 20 seconds? Please help

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.

Wavelength divides in half and speed stays the same.

It would be c hope this out
