Every 300 m thereafter or less |
$0.20 |
Rachel paid a taxi fare of $3.70. What was the greatest distance that Rachel could have travelled in the taxi? Give your answer in km.
Amount that Rachel paid for the additional distance
= 3.70 - 2.70
= $1
Number of sets of $0.20 that Rachel paid for the edditional distance
= 1 ÷ 0.20
= 5
Total additional distance that Rachel 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 Rachel could have travelled in the taxi
= 1 + 1.5
= 2.5 km
Answer(s): 2.5 km
