Taxi Fare |
|
First km |
$2.70 |
Every additional 300 m or less |
$0.37 |
Every 40 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $2.70
Remaining distance to pay for
= 9.4 - 1
= 8.4 km
1 km = 1000 m
8.4 km = 8.4 x 1000 = 8400 m
Sets of additional 300 m
= 8400 ÷ 300
= 28 r 0
Amount to pay for remaining 8.4 km
= 28 x 0.37
= $10.36
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
Cathy's taxi fare
= 2.70 + 10.36 + 1.50
= $14.56
Answer(s): $14.56
