Taxi Fare |
|
First km |
$3.30 |
Every additional 300 m or less |
$0.45 |
Every 45 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $3.30
Remaining distance to pay for
= 8.5 - 1
= 7.5 km
1 km = 1000 m
7.5 km = 7.5 x 1000 = 7500 m
Sets of additional 300 m
= 7500 ÷ 300
= 25 r 0
Amount to pay for remaining 7.5 km
= 25 x 0.45
= $11.25
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 45 seconds of waiting
= 120 ÷ 45
= 2 r 30
Sets of 45 seconds of waiting or less
= 2 + 1
= 3
Amount to pay for sets of 45 seconds of waiting or less
= 3 x 0.40
= $1.20
Gabby's taxi fare
= 3.30 + 11.25 + 1.20
= $15.75
Answer(s): $15.75
