Step-by-step explanation:
If the tub was 4.97 gallons it would take 1 minute Right?
To find the the time required to fill the tub divide volume of tub by the rate of hose. We have 336/4.97=67.605minutes
Divide by 60` 67.605/60=1.12675hours approximately
You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
