Taxi Fare |
|
First km |
$3.60 |
Every additional 500 m or less |
$0.23 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.60
Remaining distance to pay for
= 8.2 - 1
= 7.2 km
1 km = 1000 m
7.2 km = 7.2 x 1000 = 7200 m
Sets of additional 500 m
= 7200 ÷ 500
= 14 r 200
Sets of additional 500 m or less
= 14 + 1
= 15
Amount to pay for remaining 7.2 km
= 15 x 0.23
= $3.45
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 35 seconds of waiting
= 180 ÷ 35
= 5 r 5
Sets of 35 seconds of waiting or less
= 5 + 1
= 6
Amount to pay for sets of 35 seconds of waiting or less
= 6 x 0.20
= $1.20
Cathy's taxi fare
= 3.60 + 3.45 + 1.20
= $8.25
Answer(s): $8.25
