Every 500 m thereafter or less |
$0.50 |
Julie paid a taxi fare of $5.10. What was the greatest distance that Julie could have travelled in the taxi? Give your answer in km.
Amount that Julie paid for the additional distance
= 5.10 - 3.10
= $2
Number of sets of $0.50 that Julie paid for the edditional distance
= 2 ÷ 0.50
= 4
Total additional distance that Julie could have travelled in the taxi
= 4 x 500
= 2000 m
1000 m = 1 km
2000 m = 2000 ÷ 1000 = 2 km
Greatest distance that Julie could have travelled in the taxi
= 1 + 2
= 3 km
Answer(s): 3 km
