Taxi Fare |
|
First km |
$3.80 |
Every additional 500 m or less |
$0.41 |
Every 30 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.80
Remaining distance to pay for
= 5.4 - 1
= 4.4 km
1 km = 1000 m
4.4 km = 4.4 x 1000 = 4400 m
Sets of additional 500 m
= 4400 ÷ 500
= 8 r 400
Sets of additional 500 m or less
= 8 + 1
= 9
Amount to pay for remaining 4.4 km
= 9 x 0.41
= $3.69
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0
Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.20
= $0.80
Esther's taxi fare
= 3.80 + 3.69 + 0.80
= $8.29
Answer(s): $8.29
