When a car is driven 'normally' the feul consumption
is 7.5 per litres per 100km. On a particular journey the car was driven
in 'hard' and the consumption changed to 9.1 litres per 100km. Fuel cost
80p per litre. Calculate:
a) The extra feul consumed.
b) The extra cost of feul, in pounds, for the journey when the car was
driven in 'hard'.

Hi Guy,
Driving hard uses 9.1 litres per 100 km while normal dirving
uses 7.5 litres per 100 km.
9.1 - 7.5 = 1.6 and hence driving hard uses an extra
1.6 litres of fuel for each 100 km.
You didn't tell me how how far the journey was so I can't calculate the extra fuel consumed.
