Answer:
After 6 minutes the tub will be 30% full
Step-by-step explanation:
Step 1
Determine the total volume that will be filled by the faucet at time (t) using the expression below;
V=R×T
where;
V=total volume
R=flow rate, gallons per minute
T=time in minutes
In our case;
V=unknown
R=4 gallons per minute
T=6 minutes
replacing;
V=4×6=24 gallons
Total volume filled after 6 minutes=24 gallons
Step 2
Determine the percentage volume of the tab that will be filled after 6 minutes using the expression;
percentage volume=(volume filled after 6 minutes/total volume)×100
where;
volume filled after 6 minutes=24 gallons
total volume=80 gallons
replacing;
percentage volume=(24/80)×100=30%
After 6 minutes the tub will be 30% full
