Taxi Fare |
|
First km |
$3.60 |
Every additional 500 m or less |
$0.33 |
Every 35 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $3.60
Remaining distance to pay for
= 7.9 - 1
= 6.9 km
1 km = 1000 m
6.9 km = 6.9 x 1000 = 6900 m
Sets of additional 500 m
= 6900 ÷ 500
= 13 r 400
Sets of additional 500 m or less
= 13 + 1
= 14
Amount to pay for remaining 6.9 km
= 14 x 0.33
= $4.62
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 0.40
= $1.60
Barbara's taxi fare
= 3.60 + 4.62 + 1.60
= $9.82
Answer(s): $9.82
