Answer: If he goes to the town and there is not a fuel station, he can not go back to the previous fuel station.
Step-by-step explanation:
Nic can only drive for another 26 miles.
If he goes to the town, that is 8 miles away, he will have a total of:
26 - 8 = 18 miles left.
Now, the fuel station was 19 miles away from the initial position, but he is now in the town, other 8 miles away, so he is at 19 + 8 = 27 miles away from the fuel station, and he only has 18 miles left, so he can not go back to the fuel station.
