Taxi Fare |
|
First km |
$2.10 |
Every additional 300 m or less |
$0.37 |
Every 35 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $2.10
Remaining distance to pay for
= 6.7 - 1
= 5.7 km
1 km = 1000 m
5.7 km = 5.7 x 1000 = 5700 m
Sets of additional 300 m
= 5700 ÷ 300
= 19 r 0
Amount to pay for remaining 5.7 km
= 19 x 0.37
= $7.03
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 0.30
= $1.20
Sarah's taxi fare
= 2.10 + 7.03 + 1.20
= $10.33
Answer(s): $10.33
