Question

A 60-tooth gear is connected to a 72-tooth gear.if the smaller gear turns 12 times,how many turns does the larger gear make?

Answer 1

Answer : The number of turns the larger gear made, 10

Explanation :

We are given:

Let the turns made by larger gear be 'y'.

When turns 12 times then the smaller gear =
`60* 12`

When turns 'y' times then the larger gear =
`72* y`

60-tooth gear = 72-tooth gear

`60* 12=72* y`

`y=(60* 12)/(72)`

`y=10`

Therefore, the number of turns the larger gear made, 10
