Joelle paid a taxi fare of $9.80. What was the greatest distance that Joelle could have travelled in the taxi? Give your answer in km.
Amount that Joelle paid for the additional distance
= 9.80 - 4.80
= $5
Number of sets of $0.50 that Joelle paid for the edditional distance
= 5 ÷ 0.50
= 10
Total additional distance that Joelle could have travelled in the taxi
= 10 x 500
= 5000 m
1000 m = 1 km
5000 m = 5000 ÷ 1000 = 5 km
Greatest distance that Joelle could have travelled in the taxi
= 1 + 5
= 6 km
Answer(s): 6 km
