Olaf is sailing across the ocean with 25 men, including himself. He needs 1/2 a gallon of water per day per man. The boat can go 200 miles per day and he needs to travel 4,000 miles. How many gallons of water does he need?
How many gallons of water does Olaf need per day? ** He needs 12.5 gallons per day because 25 x .5 = <<25*.5=12.5>>12.5
How many days will it take to travel 4,000 miles? ** It will take 20 days of travel because 4,000 / 200 = <<4000/200=20>>20
How many gallons of water does Olaf need? ** He will need 250 gallons of water because 20 x 12.5 = <<20*12.5=250>>250
