Chloe and Nadia shared a taxi home from a shop. Their houses and the shop all lie on the same road, as shown.
The taxi journey had an initial charge of £4
plus a cost of £2 for every kilometre travelled.
a) Chloe says they should split the total cost in the same ratio as the distance each person travelled. If they did this, how much would they each pay?
b) Nadia says they should split the initial charge equally and then split the rest of the cost in the same ratio as the distance each person travelled. If they did this, how much would they each pay?
c) Chloe then says that she should pay nothing because the taxi was passing her house on the way to Nadia's house. Do you agree with this? Write a sentence to explain your answer.
