Zara paid a taxi fare of $7.40. What was the greatest distance that Zara could have travelled in the taxi? Give your answer in km.
Amount that Zara paid for the additional distance
= 7.40 - 4.40
= $3
Number of sets of $0.30 that Zara paid for the edditional distance
= 3 ÷ 0.30
= 10
Total additional distance that Zara could have travelled in the taxi
= 10 x 600
= 6000 m
1000 m = 1 km
6000 m = 6000 ÷ 1000 = 6 km
Greatest distance that Zara could have travelled in the taxi
= 1 + 6
= 7 km
Answer(s): 7 km
