Answer:
6 pumps are needed to fill the pool in 5 and 1/3 hrs.
Step-by-step explanation:
8 hrs=8×60
=480 minutes
5 and 1/3 hrs= (5×60)+(1/3×60)
=300+20
=320 minutes
To fill the pool in 480 minutes 4 pumps are needed
To fill the pool in 1 minute (4×480) pumps are needed
To fill the pool in 320 minutes (4×240)/320 pumps are needed
=6
Hence, 6 pumps are needed to fill the pool in 5 and 1/3 hrs.
