Taxi Fare |
|
First km |
$2.30 |
Every additional 500 m or less |
$0.33 |
Every 45 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $2.30
Remaining distance to pay for
= 8.9 - 1
= 7.9 km
1 km = 1000 m
7.9 km = 7.9 x 1000 = 7900 m
Sets of additional 500 m
= 7900 ÷ 500
= 15 r 400
Sets of additional 500 m or less
= 15 + 1
= 16
Amount to pay for remaining 7.9 km
= 16 x 0.33
= $5.28
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 45 seconds of waiting
= 180 ÷ 45
= 4 r 0
Amount to pay for sets of 45 seconds of waiting or less
= 4 x 0.20
= $0.80
Xandra's taxi fare
= 2.30 + 5.28 + 0.80
= $8.38
Answer(s): $8.38
