Every 700 m thereafter or less |
$0.50 |
Esther paid a taxi fare of $7.60. What was the greatest distance that Esther could have travelled in the taxi? Give your answer in km.
Amount that Esther paid for the additional distance
= 7.60 - 2.60
= $5
Number of sets of $0.50 that Esther paid for the edditional distance
= 5 ÷ 0.50
= 10
Total additional distance that Esther could have travelled in the taxi
= 10 x 700
= 7000 m
1000 m = 1 km
7000 m = 7000 ÷ 1000 = 7 km
Greatest distance that Esther could have travelled in the taxi
= 1 + 7
= 8 km
Answer(s): 8 km
