Since I have typed the same kind of thing a thousand times, I can be fairly certain that "#1 L" is supposed to be "31 L", since "#" is shift-3 on a standard keyboard.
So she used 31-11 = 20L of gas before the low fuel warning light came on. At 9.3L per 100km, the number of km she drove before the light came on was
100km
20 L * ------- = 215 km (to the nearest whole number)
9.3L
Since she drove at 100 km/h, her driving time, from her start at 1:30 pm to when the light came on, was 2.15 hours, or 2 hours 9 minutes.
ANSWER: The warning light came on at about 3:39 pm.
