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

Every 800 m thereafter or less |
$0.50 |
Kathy paid a taxi fare of $8.80. What was the greatest distance that Kathy could have travelled in the taxi? Give your answer in km.
Amount that Kathy paid for the additional distance
= 8.80 - 4.80
= $4
Number of sets of $0.50 that Kathy paid for the edditional distance
= 4 ÷ 0.50
= 8
Total additional distance that Kathy could have travelled in the taxi
= 8 x 800
= 6400 m
1000 m = 1 km
6400 m = 6400 ÷ 1000 = 6.4 km
Greatest distance that Kathy could have travelled in the taxi
= 1 + 6.4
= 7.4 km
Answer(s): 7.4 km
