A certain car can travel 40 minutes on a gallon of gasoline at 60 miles per hour. If the car had started with a full tank and had 8 gallons of gasoline left in its tank at the end, then what percent of the tank was used to travel 120 miles at 60 mph?	Pick one:
A) 15%  B) 20%  C) 27.27%  D) 30%  E) 40%
Let, Tank capacity = T gallon   Used Fuel = (T-8) gallons   Distance Travelled (@60 miles/hr) = 80 miles   Distance travelled in 1 gallon = Distance travelled in 40 mins (@60 miles/hr) = (60/60)*40= 
<gadget id="calculator">(60/60)*40</gadget>
<output>40</output>
40 miles   Fuel used to travel 120 miles= (120/40)= 
<gadget id="calculator">(120/40)</gadget>
<output>3</output>
3 gallon   i.e. Used fuel= (T-8) = 3 gallon   i.e. T = 10 Gallons   i.e. Used Fuel = (3/11)*100 =27,27%   27.27%
