Answer 4

The way I see it is that if pulley a is rotating at a speed of 600 rpm and it has a diameter of 2, then the 4 inch pulley would go around once for every two turns of the 2 inch pulley. So I would venture to say that speed or rpm of the 4" pulley is 300 rpm.

Answer 5

For the 1" pulley, I would have to say it is going around twice as much as the 2" so its rpm would be 1200. the 5" pulley is going around 2.5 times slower than as is the 2 inch pulley.

Answer 6

Or pulley 5 is going around 5 times slower than the 1" pulley. So its rpm is 1200/5 which is 240 rpm

A.) 6
