Taxi Fare |
|
First km |
$2.80 |
Every additional 400 m or less |
$0.28 |
Every 40 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.80
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 0.28
= $5.04
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 40 seconds of waiting
= 180 ÷ 40
= 4 r 20
Sets of 40 seconds of waiting or less
= 4 + 1
= 5
Amount to pay for sets of 40 seconds of waiting or less
= 5 x 0.40
= $2.00
Winnie's taxi fare
= 2.80 + 5.04 + 2.00
= $9.84
Answer(s): $9.84
