A car can average 140 miles on 5 gallons of gasoline. Write an equation for the distance "d" in miles the car can tavel on "g" gallons of gas?

140mi / 5gal = 28mi/gal.

d = 28 * g.

D=5g

To write an equation that represents the distance a car can travel on a given amount of gallons of gas, we can use the information given in the problem.

According to the problem, the car can average 140 miles on 5 gallons of gasoline. We can use this information to find the average number of miles the car can travel on each gallon of gas.

To calculate this, we divide the total number of miles (140) by the total number of gallons (5):

Average miles per gallon = total miles / total gallons
Average miles per gallon = 140 miles / 5 gallons
Average miles per gallon = 28 miles per gallon

Now, we can use this information to write the equation for the distance "d" in miles the car can travel on "g" gallons of gas.

The equation would be:
d = 28g

In this equation, "d" represents the distance in miles and "g" represents the number of gallons of gas.
