Detailed Solution

72. The differences (in kilometres per litre) are:

Toyota Prius 19 - 20 = -1
Hundai Sonata 13 - 9 = 5
Lamborghini Murcielago 6 - 3 = 3
Mercedes Benz E83 AMG 8 - 6 = 2

The Hundai Sonata had the greatest difference.

73. The priustravels 20 km per litre in the city, so would use 3 litres of petrol to travel 60 km.
TheMercedes Benz travels 6 km per litre in the city, so 3 litrs would be enough to travel 3 x 6 = 18 km.

74. The number of litres used in the city = 36/9 = 4
The number of litres used on the open road = 154/11 = 14
Therefore Total number of litres used = 18
Therefore Cost = 18 x 95 p = 17.10 Pounds.

75. The number of litres used by the Hundai = 210/14 = 15
Therefore cost in Hundai = 15 x 95p = 14.25 Pounds
The number of litres used by the Lamborghini = 210/6 = 35
Therefore cost in Lamborghini = 35 x 101p = 35.35 Pounds
Therefore extra cost = 35.35 - 14.25 = 21.10 Pounds
