Name_________________________ At the
construction site two apprentices are trying to hoist a bucket of
cement on a
pulley up to Mary, the master mason, at the top of a scaffolding 20' up. The two apprentices are having a bit of
trouble keeping a grip on the rope of the pulley. Each
time the two of them pull on the
rope, the bucket goes up 5', but they have trouble holding it tight and
the
bucket always slips down one foot after each pull.
How many pulls will it take for the
bucket to reach Mary?
Get
a Grip!
Good Luck!!!!!
