Question

Ann and Milan are driving separate cars to New York. They begin the trip with full gas tanks. The amount of gas (in gallons) remaining in the tank of each car depends on the number of miles driven, as shown below.After 225 miles driven, which car will have less gas remaining?After how many miles will the tanks contain the same amount of gas? If the number of miles driven is less than this, which car will have more gas remaining?

Answer 1

Ann began with 16 gallons of gas

Milan began with 20 gallons of gas

1.After 225 miles driven, Milan car has less gas remaining = 5 gallons , wheras Ann's car is at 7 gallons.

2. After 150 miles , the cars will have same amount of gas , this is their point of intersection on the graph .

3. at less than 150 miles, Milans car / graph is above Ann's car, meaning Milan car will have more gas remaining at less than 150 miles .
