Representations of linear functions
Fuel efficiency
|
A family went on a long trip. Before
leaving town, they filled up the car
at a gas station near home. The graph below
shows the dependence of the amount
of fuel left in the tank on the distance they drove.
|
|
|
fuel in tank (liters) |
| distance (kilometers) |
|
|  |
|
Describe the dependence of the amount of fuel remaining in the tank
on the distance driven. Use words,
a value table, and a correspondence rule.
|
|
What is the capacity of the tank (the amount of fuel in the tank when it is
full)?
|
|
|
How many kilometers can the car drive on 1 liter of gas (the car's fuel efficiency)?
| |
| What is the greatest distance the family can drive before having to refuel?
| |
Describe how the graph would change if:
- The tank capacity were increased.
- The fuel efficiency were increased.
