Taxi Fare |
|
First km |
$3.40 |
Every additional 500 m or less |
$0.42 |
Every 45 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.40
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 500 m
= 8600 ÷ 500
= 17 r 100
Sets of additional 500 m or less
= 17 + 1
= 18
Amount to pay for remaining 8.6 km
= 18 x 0.42
= $7.56
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 45 seconds of waiting
= 180 ÷ 45
= 4 r 0
Amount to pay for sets of 45 seconds of waiting or less
= 4 x 0.20
= $0.80
Mary's taxi fare
= 3.40 + 7.56 + 0.80
= $11.76
Answer(s): $11.76
