Answer:
6.25 hours
Step-by-step explanation:
The volume (V) of the tank is calculated as
V = lbh ( l is length, b is width and h is height ), thus
V = 5 × 1.5 × 3 = 22.5 m³
Divide V by rate for time in minutes
Time = 22.5 ÷ 0.06 = 375 minutes
Divide minutes by 60 to convert to hours, that is
Time to fill tank = 375 ÷ 60 = 6.25 hours
