Winnie paid a taxi fare of $12.20. What was the greatest distance that Winnie could have travelled in the taxi? Give your answer in km.
Amount that Winnie paid for the additional distance
= 12.20 - 4.20
= $8
Number of sets of $0.80 that Winnie paid for the edditional distance
= 8 ÷ 0.80
= 10
Total additional distance that Winnie could have travelled in the taxi
= 10 x 200
= 2000 m
1000 m = 1 km
2000 m = 2000 ÷ 1000 = 2 km
Greatest distance that Winnie could have travelled in the taxi
= 1 + 2
= 3 km
Answer(s): 3 km
