To find how long it will take to fill the tank, you can use the idea that every 30 seconds will get you one gallon closer to being full.
This means to fill 50 gallons, you will need 50 groups of 30 seconds.
50 x 30 = 1500 seconds
1500/60 = 25 minutes.
It will take 25 minutes.
You could also think of it as filling 2 gallons every minute. It would take 25 of these.
G and c you see look 2 times and look at the lines
To answer this you will need to determine which area made with the 12 square tiles would give the shortest perimeter.
Think of all the combinations to get 12 square inches
1x12, 2x6, and 3x4. The perimeters of these are 26 in, 16 in, and 14 in.
You should arrange your tiles using the 3 x 4 option. You would need 14 stones.
To round to the nearest tenth place you are going to round the last two digits of that, you should get 519.7
