Taxi Fare |
|
First km |
$3.50 |
Every additional 300 m or less |
$0.27 |
Every 40 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.50
Remaining distance to pay for
= 8.4 - 1
= 7.4 km
1 km = 1000 m
7.4 km = 7.4 x 1000 = 7400 m
Sets of additional 300 m
= 7400 ÷ 300
= 24 r 200
Sets of additional 300 m or less
= 24 + 1
= 25
Amount to pay for remaining 7.4 km
= 25 x 0.27
= $6.75
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 40 seconds of waiting
= 120 ÷ 40
= 3 r 0
Amount to pay for sets of 40 seconds of waiting or less
= 3 x 0.20
= $0.60
Xandra's taxi fare
= 3.50 + 6.75 + 0.60
= $10.85
Answer(s): $10.85
