Hilda paid a taxi fare of $4.70. What was the greatest distance that Hilda could have travelled in the taxi? Give your answer in km.
Amount that Hilda paid for the additional distance
= 4.70 - 2.70
= $2
Number of sets of $0.50 that Hilda paid for the edditional distance
= 2 ÷ 0.50
= 4
Total additional distance that Hilda could have travelled in the taxi
= 4 x 400
= 1600 m
1000 m = 1 km
1600 m = 1600 ÷ 1000 = 1.6 km
Greatest distance that Hilda could have travelled in the taxi
= 1 + 1.6
= 2.6 km
Answer(s): 2.6 km
