Not exactly what you asked for, but an A319 (similar size as B717) burns approx 10kgs per nm as trip fuel. So LHR-MAN (160nm = 1600kgs)
In your example, 110 nautical miles = 1100kgs = 1375 litres of fuel, or less by about 15% if you are talking statute miles.
I'll let you convert to your version of the gallon
