Taxi Fare |
|
First km |
$3.70 |
Every additional 400 m or less |
$0.34 |
Every 45 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.70
Remaining distance to pay for
= 9.6 - 1
= 8.6 km
1 km = 1000 m
8.6 km = 8.6 x 1000 = 8600 m
Sets of additional 400 m
= 8600 ÷ 400
= 21 r 200
Sets of additional 400 m or less
= 21 + 1
= 22
Amount to pay for remaining 8.6 km
= 22 x 0.34
= $7.48
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 45 seconds of waiting
= 120 ÷ 45
= 2 r 30
Sets of 45 seconds of waiting or less
= 2 + 1
= 3
Amount to pay for sets of 45 seconds of waiting or less
= 3 x 0.20
= $0.60
Emma's taxi fare
= 3.70 + 7.48 + 0.60
= $11.78
Answer(s): $11.78
