Tammy paid a taxi fare of $4.50. 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
= 4.50 - 2.50
= $2
Number of sets of $0.50 that Tammy paid for the edditional distance
= 2 ÷ 0.50
= 4
Total additional distance that Tammy could have travelled in the taxi
= 4 x 600
= 2400 m
1000 m = 1 km
2400 m = 2400 ÷ 1000 = 2.4 km
Greatest distance that Tammy could have travelled in the taxi
= 1 + 2.4
= 3.4 km
Answer(s): 3.4 km
