Nora paid a taxi fare of $7.80. What was the greatest distance that Nora could have travelled in the taxi? Give your answer in km.
Amount that Nora paid for the additional distance
= 7.80 - 3.80
= $4
Number of sets of $0.80 that Nora paid for the edditional distance
= 4 ÷ 0.80
= 5
Total additional distance that Nora could have travelled in the taxi
= 5 x 300
= 1500 m
1000 m = 1 km
1500 m = 1500 ÷ 1000 = 1.5 km
Greatest distance that Nora could have travelled in the taxi
= 1 + 1.5
= 2.5 km
Answer(s): 2.5 km
