A motorcycle has a reserved fuel of 0.5 liter which can be used if its 3-liter
fuel tank is about to be emptied. The motorcycle consumes at most 0.5 liters
of fuel for every 20 km of travel.
a. What mathematical statement represents the amount of fuel that
would be left in the motorcycle’s fuel tank after travelling a certain
distance if its tank is full at the start of travel?
b. Suppose the motorcycle’s tank is full and it travels a distance of 55 km,
about how much fuel would be left in its tank?
c. If the motorcycle travels a distance of 130 km with its tank full, is the
amount of fuel in its tank be enough to cover the given distance?

Answer:
1. For every 20 kilometers traveled the motorcycle would consume 0.5 liters of fuel.
2. There would still be at least 1.7 liters of fuel.
3. No it would not cover the distance at all, since the 3 liter fuel tank only compensates to a distance of 120 kilometers.
