Esther paid a taxi fare of $4.70. What was the greatest distance that Esther could have travelled in the taxi? Give your answer in km.
Amount that Esther paid for the additional distance
= 4.70 - 2.70
= $2
Number of sets of $0.50 that Esther paid for the edditional distance
= 2 ÷ 0.50
= 4
Total additional distance that Esther could have travelled in the taxi
= 4 x 700
= 2800 m
1000 m = 1 km
2800 m = 2800 ÷ 1000 = 2.8 km
Greatest distance that Esther could have travelled in the taxi
= 1 + 2.8
= 3.8 km
Answer(s): 3.8 km
