Taxi Fare |
|
First km |
$2.20 |
Every additional 300 m or less |
$0.38 |
Every 40 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $2.20
Remaining distance to pay for
= 7.9 - 1
= 6.9 km
1 km = 1000 m
6.9 km = 6.9 x 1000 = 6900 m
Sets of additional 300 m
= 6900 ÷ 300
= 23 r 0
Amount to pay for remaining 6.9 km
= 23 x 0.38
= $8.74
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 40 seconds of waiting
= 180 ÷ 40
= 4 r 20
Sets of 40 seconds of waiting or less
= 4 + 1
= 5
Amount to pay for sets of 40 seconds of waiting or less
= 5 x 0.30
= $1.50
Gabby's taxi fare
= 2.20 + 8.74 + 1.50
= $12.44
Answer(s): $12.44
