Kimberly paid a taxi fare of $11.60. What was the greatest distance that Kimberly could have travelled in the taxi? Give your answer in km.
Amount that Kimberly paid for the additional distance
= 11.60 - 3.60
= $8
Number of sets of $0.80 that Kimberly paid for the edditional distance
= 8 ÷ 0.80
= 10
Total additional distance that Kimberly could have travelled in the taxi
= 10 x 800
= 8000 m
1000 m = 1 km
8000 m = 8000 ÷ 1000 = 8 km
Greatest distance that Kimberly could have travelled in the taxi
= 1 + 8
= 9 km
Answer(s): 9 km
