Taxi Fare |
|
First km |
$2.60 |
Every additional 300 m or less |
$0.38 |
Every 35 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.60
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 300 m
= 6800 ÷ 300
= 22 r 200
Sets of additional 300 m or less
= 22 + 1
= 23
Amount to pay for remaining 6.8 km
= 23 x 0.38
= $8.74
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 0.40
= $1.60
Cathy's taxi fare
= 2.60 + 8.74 + 1.60
= $12.94
Answer(s): $12.94
