Taxi Fare |
|
First km |
$2.60 |
Every additional 500 m or less |
$0.31 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $2.60
Remaining distance to pay for
= 8.6 - 1
= 7.6 km
1 km = 1000 m
7.6 km = 7.6 x 1000 = 7600 m
Sets of additional 500 m
= 7600 ÷ 500
= 15 r 100
Sets of additional 500 m or less
= 15 + 1
= 16
Amount to pay for remaining 7.6 km
= 16 x 0.31
= $4.96
1 min = 60 s
2 min = 2 x 60 = 120 s
Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15
Sets of 35 seconds of waiting or less
= 3 + 1
= 4
Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.20
= $0.80
Betty's taxi fare
= 2.60 + 4.96 + 0.80
= $8.36
Answer(s): $8.36
