A taxi service charges the following rates:
Distance travelled |
Charge |
First kilometre or less |
$2.40 |
Every 600 m thereafter or less |
$0.80 |
Anna paid a taxi fare of $6.40. What was the greatest distance that Anna could have travelled in the taxi? Give your answer in km.
Amount that Anna paid for the additional distance
= 6.40 - 2.40
= $4
Number of sets of $0.80 that Anna paid for the edditional distance
= 4 ÷ 0.80
= 5
Total additional distance that Anna could have travelled in the taxi
= 5 x 600
= 3000 m
1000 m = 1 km
3000 m = 3000 ÷ 1000 = 3 km
Greatest distance that Anna could have travelled in the taxi
= 1 + 3
= 4 km
Answer(s): 4 km
