Taxi Fare |
|
First km |
$2.30 |
Every additional 500 m or less |
$0.22 |
Every 30 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.30
Remaining distance to pay for
= 6.9 - 1
= 5.9 km
1 km = 1000 m
5.9 km = 5.9 x 1000 = 5900 m
Sets of additional 500 m
= 5900 ÷ 500
= 11 r 400
Sets of additional 500 m or less
= 11 + 1
= 12
Amount to pay for remaining 5.9 km
= 12 x 0.22
= $2.64
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 30 seconds of waiting
= 180 ÷ 30
= 6 r 0
Amount to pay for sets of 30 seconds of waiting or less
= 6 x 0.40
= $2.40
Sarah's taxi fare
= 2.30 + 2.64 + 2.40
= $7.34
Answer(s): $7.34
