Question

Karl set out to Alaska on his truck.

Answer 1

Answer:

the amount of fuel consumed every 100 kilometers is 62.5 litres.

Step-by-step explanation:

To determine the amount of fuel consumed every 100 kilometers.

Note: since the graph is a straight line graph (linear graph) the amount of fuel consumed every 100 kilometers is constant (i.e the same for every 100 kilometers). So, we only need to derive the amount of fuel consumed any 100 kilometers on the graph.

From the graph, the amount of fuel consumed for the first 100 kilometers is;

$F = F_0 - F_{100} .........................1$

$F_0 = 500\\F_{100} \simeq 437.5$

substituting into equation 1.

$F = F_0 - F_{100} \\F = 500 - 437.5\\ F = 62.5 litres$

Therefore, the amount of fuel consumed every 100 kilometers is 62.5 litres.

Answer 2

Answer:

the answer is 500 kilometers

Step-by-step explanation:

To find the distance that corresponds to 200 liters of fuel, we need to look for the point on the graph where Fuel is 200. The point we are looking for is (500,200), which means that after driving for 500 kilometers, the truck had 200 liters of fuel remaining
