Answer:
Explanation:
Let's call the number of gallons of gas "g" and the number of miles the car can drive "m".
From the given information, we know that the car can drive 40 miles on 1 gallon of gas. So, we can write the following proportion:
40 miles / 1 gallon = m miles / g gallons
We can solve for m by cross-multiplying and simplifying:
40 miles * g gallons = 1 gallon * m miles
m = 40g
Therefore, the function rule to represent the number of miles the car can drive on any amount of gas is:
m(g) = 40g
This function is linear, with a slope of 40, which means that for every additional gallon of gas, the car can travel an additional 40 miles.
