Taxi Fare |
|
First km |
$3.40 |
Every additional 500 m or less |
$0.33 |
Every 40 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $3.40
Remaining distance to pay for
= 7.8 - 1
= 6.8 km
1 km = 1000 m
6.8 km = 6.8 x 1000 = 6800 m
Sets of additional 500 m
= 6800 ÷ 500
= 13 r 300
Sets of additional 500 m or less
= 13 + 1
= 14
Amount to pay for remaining 6.8 km
= 14 x 0.33
= $4.62
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 40 seconds of waiting
= 120 ÷ 40
= 3 r 0
Amount to pay for sets of 40 seconds of waiting or less
= 3 x 0.30
= $0.90
Rachel's taxi fare
= 3.40 + 4.62 + 0.90
= $8.92
Answer(s): $8.92
