======================================================
Work Shown:
1 liter = 1000 cubic cm
45 liters = 45*1000 = 45000 cubic cm
The container has a capacity of 45000 cubic cm
It will take 45000/2 = 22500 seconds to fill the container since the rate is 2 cubic cm per second.
-----------------
Convert from seconds to minutes
22500 seconds = (22500)*(1 min/60 sec)
22500 seconds = (22500/60) min
22500 seconds = 375 min
-----------------
Convert to hours
375 min = (375)*(1 hr/60 min)
375 min = (375/60) hr
375 min = 6.25 hr
----------------
Converting to hours,minutes
6.25 hr = 6 hr + 0.25 hr
6.25 hr = 6 hr + (0.25*60) min
6.25 hr = 6 hr + 15 min
6.25 hr = 6 hr, 15 min
