Taxi Fare |
|
First km |
$2.10 |
Every additional 400 m or less |
$0.34 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $2.10
Remaining distance to pay for
= 9.9 - 1
= 8.9 km
1 km = 1000 m
8.9 km = 8.9 x 1000 = 8900 m
Sets of additional 400 m
= 8900 ÷ 400
= 22 r 100
Sets of additional 400 m or less
= 22 + 1
= 23
Amount to pay for remaining 8.9 km
= 23 x 0.34
= $7.82
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
Yen's taxi fare
= 2.10 + 7.82 + 0.80
= $10.72
Answer(s): $10.72
