Taxi Fare |
|
First km |
$3.20 |
Every additional 500 m or less |
$0.36 |
Every 40 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $3.20
Remaining distance to pay for
= 6.4 - 1
= 5.4 km
1 km = 1000 m
5.4 km = 5.4 x 1000 = 5400 m
Sets of additional 500 m
= 5400 ÷ 500
= 10 r 400
Sets of additional 500 m or less
= 10 + 1
= 11
Amount to pay for remaining 5.4 km
= 11 x 0.36
= $3.96
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 40 seconds of waiting
= 120 ÷ 40
= 3 r 0
Amount to pay for sets of 40 seconds of waiting or less
= 3 x 0.30
= $0.90
Barbara's taxi fare
= 3.20 + 3.96 + 0.90
= $8.06
Answer(s): $8.06
