Julie paid a taxi fare of $7.20. 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
= 7.20 - 4.20
= $3
Number of sets of $0.60 that Julie paid for the edditional distance
= 3 ÷ 0.60
= 5
Total additional distance that Julie could have travelled in the taxi
= 5 x 500
= 2500 m
1000 m = 1 km
2500 m = 2500 ÷ 1000 = 2.5 km
Greatest distance that Julie could have travelled in the taxi
= 1 + 2.5
= 3.5 km
Answer(s): 3.5 km
