Taxi Fare |
|
First km |
$3.80 |
Every additional 400 m or less |
$0.26 |
Every 30 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $3.80
Remaining distance to pay for
= 6.8 - 1
= 5.8 km
1 km = 1000 m
5.8 km = 5.8 x 1000 = 5800 m
Sets of additional 400 m
= 5800 ÷ 400
= 14 r 200
Sets of additional 400 m or less
= 14 + 1
= 15
Amount to pay for remaining 5.8 km
= 15 x 0.26
= $3.90
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0
Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.30
= $1.20
Barbara's taxi fare
= 3.80 + 3.90 + 1.20
= $8.90
Answer(s): $8.90
