When full, one of the tanks at Sea World will hold 148,000 gallons of water. The tank currently has 85,000 gallons of water and is being filled at a rate of 120 gallons per minute. Write and solve an equation that can be used to find the number of hours it will take to fill the tank from its current level.

120 x 60 = 7,200 gallons.

148,000 - 85,000 = 63,000 gallons.

63,000 divided by 7,200 = 8.75  

It will take 8 hours and 45 minutes to fill the tank.

Step-by-step explanation:

120 gallons per minute would equal to 7,200 gallons an hour.

148,000 gallons - 85,000 gallons = 63,000 gallons. 63,000 gallons of water is how much is needed to reach the tanks capacity.

63,000 gallons divided by 7,200 gallons would be 8.75. That means it will take 8 hours and 45 minutes to fill the tank from 85,000 gallons.

I don't know if you need a more simplified equation, but I hope this helps in some way.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
