Answer:
6 Gallons of Paint
Step-by-step explanation:
If you use a half gallon of paint to cover 84 square feet, how much could you paint with a full gallon? Lets figure it out:
multiply both sides by 2 so that the 1/2 gallon is now 1 gallon:
1 gallon = 168 square feet
now, how many gallons does it take to paint 932 square feet?
Divide 932 by 168:
Just like you cant buy 2.374 cheeseburgers, you cant buy 5.548 gallons of something so we round up and will have some paint left over once the job is done. So 6 gallons is the answer
You would need to find out how much feet he dropped in the space of 3 mins by subtracting 2,100 and 150 that will give you 1950 then you divide that by 3 which count as your minutes and you get 650 feet per minute
