Dan works 5 days a week. Is it cheaper to use car or bus? Bus weekly ticket = £19.50. Car drive is 24.2 miles, car does 32.3 miles per gallon of petrol, which costs £1.27 per litre. Use 1 gallon = 4.5 litres
Work out how many miles Dan does in a week if he drove. 24.2 x 5 = 121Work out how many gallons of petrol this would be. 121/32.3 = 3.746130031Convert into litres. 3.746130031 x 4.5 = 16.85758514Work out the cost of petrol. 16.85758514 x £1.27 = £21.41 (after rounding)Compare costs: £21.41 > £19.50 hence bus is cheaper.
