Answer:If Deon uses 5 gallons of gas, he would drive a distance of D = 30g = 30 * 5 = 150 miles.
Step-by-step explanation:Deon drives a distance of 150 miles when he uses 5 gallons of gas because the equation D = 30g represents the relationship between the distance (D) and the number of gallons of gas (g) he uses. When we substitute g with 5, we get D = 30 * 5 = 150 miles.
