Taxi Fare |
|
First km |
$2.30 |
Every additional 400 m or less |
$0.21 |
Every 35 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.30
Remaining distance to pay for
= 8.2 - 1
= 7.2 km
1 km = 1000 m
7.2 km = 7.2 x 1000 = 7200 m
Sets of additional 400 m
= 7200 ÷ 400
= 18 r 0
Amount to pay for remaining 7.2 km
= 18 x 0.21
= $3.78
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
= 2.30 + 3.78 + 1.60
= $7.68
Answer(s): $7.68
