Ivory paid a taxi fare of $5.80. What was the greatest distance that Ivory could have travelled in the taxi? Give your answer in km.
Amount that Ivory paid for the additional distance
= 5.80 - 2.80
= $3
Number of sets of $0.30 that Ivory paid for the edditional distance
= 3 ÷ 0.30
= 10
Total additional distance that Ivory could have travelled in the taxi
= 10 x 300
= 3000 m
1000 m = 1 km
3000 m = 3000 ÷ 1000 = 3 km
Greatest distance that Ivory could have travelled in the taxi
= 1 + 3
= 4 km
Answer(s): 4 km
