PSLE Kathy took a taxi from her office to her home. Her taxi fare was based on the charges shown. The taxi stopped once at a traffic light for 3 minutes and travelled a total distance of 4.1 km to reach Kathy's home. How much was her taxi fare?
Taxi Fare |
|
First km |
$3.50 |
Every additional 400 m or less |
$0.29 |
Every 45 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $3.50
Remaining distance to pay for
= 4.1 - 1
= 3.1 km
1 km = 1000 m
3.1 km = 3.1 x 1000 = 3100 m
Sets of additional 400 m
= 3100 ÷ 400
= 7 r 300
Sets of additional 400 m or less
= 7 + 1
= 8
Amount to pay for remaining 3.1 km
= 8 x 0.29
= $2.32
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 0.40
= $1.60
Kathy's taxi fare
= 3.50 + 2.32 + 1.60
= $7.42
Answer(s): $7.42
