Taxi Fare |
|
First km |
$3.90 |
Every additional 500 m or less |
$0.27 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.90
Remaining distance to pay for
= 6.9 - 1
= 5.9 km
1 km = 1000 m
5.9 km = 5.9 x 1000 = 5900 m
Sets of additional 500 m
= 5900 ÷ 500
= 11 r 400
Sets of additional 500 m or less
= 11 + 1
= 12
Amount to pay for remaining 5.9 km
= 12 x 0.27
= $3.24
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
Cindy's taxi fare
= 3.90 + 3.24 + 0.80
= $7.94
Answer(s): $7.94
