Question

A warehouse worker moved 108 pallets in 4.5 hours. In minutes, what is the rate to move one pallet? The worker will be off the clock in 2 hours. How many pallets can he move before quitting time?

Answer 1

The answer is 2.5 minutes; 48 pallets

Explanation:

Number of pallets worker moved in a warehouse = 108

Number of hours it takes to do so = 4.5

Rate at which they require to move one pallet is given by

Number of pallets worker moved in a warehouse = 108

Number of hours it takes to do so = 4.5

Rate at which they require to move one pallet is given by

4.5/108 x 60 minutes = 2.5 minutes

Now, if the worker will be off the clock in 2 hours ,

So, number of pallets he can move before quitting time is given by

In 4.5 hours, number of pallets they moved = 108

In 1 hour, number of pallets they moved = 108/4.5 = 24

In 2 hours, number of pallets they moved = 24 x 2 = 48

Answer 2

Number of pallets moved in 4.5 hours = 108

converting 4.5 hours in minutes we get,

4*60 + 0.5*60 = 240+30 = 270 minutes

So, 108 pallets were moved in = 270 minutes

1 pallet was moved in =
`(270)/(108)=2.5` minutes

As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be =
`(120)/(2.5)= 48` pallets.

Hence, 48 pallets can be moved before quitting time.
