Diana paid a taxi fare of $6.60. What was the greatest distance that Diana could have travelled in the taxi? Give your answer in km.
Amount that Diana paid for the additional distance
= 6.60 - 4.60
= $2
Number of sets of $0.40 that Diana paid for the edditional distance
= 2 ÷ 0.40
= 5
Total additional distance that Diana could have travelled in the taxi
= 5 x 400
= 2000 m
1000 m = 1 km
2000 m = 2000 ÷ 1000 = 2 km
Greatest distance that Diana could have travelled in the taxi
= 1 + 2
= 3 km
Answer(s): 3 km
