A commuter travels from suburb X to city centre Y. Two possible routes are available:

Route 1 - Direct bus: distance 15 km, average speed 30 km h⁻¹, average waiting time 5 min, fare £2.

Route 2 - Train then bus: train leg 8 km at 60 km h⁻¹, waiting 2 min; bus leg from the train station Z to Y is 7 km at 35 km h⁻¹, waiting 4 min; changing between train and bus adds a 3 min transfer penalty. The train fare is £1.5 and the bus fare from Z to Y is £1.2.

Which route gives the shorter total travel time and which route is cheaper?
