Taxi Fare |
|
First km |
$3.20 |
Every additional 400 m or less |
$0.42 |
Every 30 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $3.20
Remaining distance to pay for
= 5.5 - 1
= 4.5 km
1 km = 1000 m
4.5 km = 4.5 x 1000 = 4500 m
Sets of additional 400 m
= 4500 ÷ 400
= 11 r 100
Sets of additional 400 m or less
= 11 + 1
= 12
Amount to pay for remaining 4.5 km
= 12 x 0.42
= $5.04
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
Vanessa's taxi fare
= 3.20 + 5.04 + 1.20
= $9.44
Answer(s): $9.44
