Taxi Fare |
|
First km |
$2.40 |
Every additional 500 m or less |
$0.31 |
Every 35 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.40
Remaining distance to pay for
= 4.7 - 1
= 3.7 km
1 km = 1000 m
3.7 km = 3.7 x 1000 = 3700 m
Sets of additional 500 m
= 3700 ÷ 500
= 7 r 200
Sets of additional 500 m or less
= 7 + 1
= 8
Amount to pay for remaining 3.7 km
= 8 x 0.31
= $2.48
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 0.40
= $2.40
Zoe's taxi fare
= 2.40 + 2.48 + 2.40
= $7.28
Answer(s): $7.28
