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?

Number of pallets moved in 4.5 hours = 108converting 4.5 hours in minutes we get,4*60 + 0.5*60 = 240+30 = 270 minutesSo, 108 pallets were moved in = 270 minutes1 pallet was moved in = [tex]\frac{270}{108}=2.5[/tex] minutesAs the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = [tex]\frac{120}{2.5}= 48[/tex] pallets.Hence, 48 pallets can be moved before quitting time.
