A taxi service charges the following rates:
Distance travelled |
Charge |
First kilometre or less |

Every 700 m thereafter or less |
$0.40 |
Victoria paid a taxi fare of $5.50. What was the greatest distance that Victoria could have travelled in the taxi? Give your answer in km.
Amount that Victoria paid for the additional distance
= 5.50 - 3.50
= $2
Number of sets of $0.40 that Victoria paid for the edditional distance
= 2 ÷ 0.40
= 5
Total additional distance that Victoria could have travelled in the taxi
= 5 x 700
= 3500 m
1000 m = 1 km
3500 m = 3500 ÷ 1000 = 3.5 km
Greatest distance that Victoria could have travelled in the taxi
= 1 + 3.5
= 4.5 km
Answer(s): 4.5 km
