Kylie paid a taxi fare of $6.20. What was the greatest distance that Kylie could have travelled in the taxi? Give your answer in km.
Amount that Kylie paid for the additional distance
= 6.20 - 3.20
= $3
Number of sets of $0.60 that Kylie paid for the edditional distance
= 3 ÷ 0.60
= 5
Total additional distance that Kylie 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 Kylie could have travelled in the taxi
= 1 + 3.5
= 4.5 km
Answer(s): 4.5 km
