Answer:Since we know the boat uses 25 gallons of gas per 64 miles, we can divide 64 miles by 25 gallons to get the rate of gallons per hour.
64 รท 25 = 2.56 gallons of gas every hour.
Using this information, we can multiply the amount of gas used for one hour, 2.56 gallons, by the 125 gallons of gas that the problem suggests, 125, to find the number of miles the boat can travel on the amount of gas.
2.56 x 125 = 320 miles
Answer: The boat can travel 320 miles on 125 gallons of gas.
