Taxi Fare |
|
First km |
$3.20 |
Every additional 400 m or less |
$0.41 |
Every 30 seconds waiting or less |
$0.40 |
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 400 m
= 5400 ÷ 400
= 13 r 200
Sets of additional 400 m or less
= 13 + 1
= 14
Amount to pay for remaining 5.4 km
= 14 x 0.41
= $5.74
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 0.40
= $1.60
Risa's taxi fare
= 3.20 + 5.74 + 1.60
= $10.54
Answer(s): $10.54
