Tammy paid a taxi fare of $4.60. What was the greatest distance that Tammy could have travelled in the taxi? Give your answer in km.
Amount that Tammy paid for the additional distance
= 4.60 - 2.60
= $2
Number of sets of $0.40 that Tammy paid for the edditional distance
= 2 ÷ 0.40
= 5
Total additional distance that Tammy could have travelled in the taxi
= 5 x 800
= 4000 m
1000 m = 1 km
4000 m = 4000 ÷ 1000 = 4 km
Greatest distance that Tammy could have travelled in the taxi
= 1 + 4
= 5 km
Answer(s): 5 km
