Pamela paid a taxi fare of $6.80. What was the greatest distance that Pamela could have travelled in the taxi? Give your answer in km.
Amount that Pamela paid for the additional distance
= 6.80 - 2.80
= $4
Number of sets of $0.80 that Pamela paid for the edditional distance
= 4 ÷ 0.80
= 5
Total additional distance that Pamela could have travelled in the taxi
= 5 x 700
= 3500 m
1000 m = 1 km
3500 m = 3500 ÷ 1000 = 3.5 km
Greatest distance that Pamela could have travelled in the taxi
= 1 + 3.5
= 4.5 km
Answer(s): 4.5 km
