<h2>It takes 3 hours to empty the tank when the pumping rate is 180 gallons per hour.</h2>
Step-by-step explanation:
The time t (in hours) that it takes a pump to empty a tank of water varies inversely with the pumping rate r (in gallons per hour).
where k is a constant.
It takes 9 hours to empty a tank of water when the pumping rate is 60 gallons per hour.
We need to find how long does it take to empty the tank when the pumping rate is 180 gallons per hour ( r = 180)
We have
It takes 3 hours to empty the tank when the pumping rate is 180 gallons per hour.
Answer:
52 23/24
Step-by-step explanation:
31 x 41 / 8 x 3
1271 / 8 x 3
1271 / 24
convert to mixed fraction
52 23/24
If the answer is supposed to be an equation, it should be -5(+)v
1 time=2mins
xtimes=30mins
30/2 ×1= 15.
Therefore it can be completed 15 times in 30mins
