Taxi Fare |
|
First km |
$3.80 |
Every additional 400 m or less |
$0.37 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.80
Remaining distance to pay for
= 9.7 - 1
= 8.7 km
1 km = 1000 m
8.7 km = 8.7 x 1000 = 8700 m
Sets of additional 400 m
= 8700 ÷ 400
= 21 r 300
Sets of additional 400 m or less
= 21 + 1
= 22
Amount to pay for remaining 8.7 km
= 22 x 0.37
= $8.14
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15
Sets of 35 seconds of waiting or less
= 3 + 1
= 4
Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.20
= $0.80
Xylia's taxi fare
= 3.80 + 8.14 + 0.80
= $12.74
Answer(s): $12.74
