Vanessa paid a taxi fare of $9.80. What was the greatest distance that Vanessa could have travelled in the taxi? Give your answer in km.
Amount that Vanessa paid for the additional distance
= 9.80 - 2.80
= $7
Number of sets of $0.70 that Vanessa paid for the edditional distance
= 7 ÷ 0.70
= 10
Total additional distance that Vanessa could have travelled in the taxi
= 10 x 700
= 7000 m
1000 m = 1 km
7000 m = 7000 ÷ 1000 = 7 km
Greatest distance that Vanessa could have travelled in the taxi
= 1 + 7
= 8 km
Answer(s): 8 km
