1 Here is part of a train timetable for a journey from London to Marseille. All times given are in local time. The local time in Marseille is 1 hour ahead of the local time in London.

London 07 19

Ashford 07 55

Lyon 13 00

Avignon 14 08

Marseille 14 46

(a) (i) Work out the total journey time from London to Marseille. Give your answer in hours and minutes.

.................. h ...................... min [2]

(ii) The distance from London to Ashford is 90 km. The local time in London is the same as the local time in Ashford.

Work out the average speed, in km/h, of the train between London and Ashford.

...................................... km/h [3]

(iii) During the journey, the train takes 35 seconds to completely cross a bridge. The average speed of the train during this crossing is 90 km/h. The length of the train is 95 metres.

Calculate the length, in metres, of this bridge.

(b) The fares for the train journey are shown in the table below.

From London to Marseille Standard fare Premier fare

Adult $84 $140

Child $60 $96

(i) For the standard fare, write the ratio adult fare : child fare in its simplest form.

..................... : ..................... [1]

(ii) For an adult, find the percentage increase in the cost of the standard fare to the premier fare.

........................................... % [3]

(iii) For one journey from London to Marseille, the ratio

number of adults : number of children = 11 : 2.

There were 220 adults in total on this journey. All of the children and 70% of the adults paid the standard fare. The remaining adults paid the premier fare.

Calculate the total of the fares paid by the adults and the children.

$ .............................................. [5]

(c) There were 3.08 # 105 passengers that made this journey in 2018. This was a 12% decrease in the number of passengers that made this journey in 2017.

Find the number of passengers that made this journey in 2017. Give your answer in standard form.
