PSLE Sarah 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 4.3 km to reach Sarah's home. How much was her taxi fare?
Taxi Fare |
|
First km |
$2.80 |
Every additional 300 m or less |
$0.21 |
Every 40 seconds waiting or less |
$0.30 |
Amount to pay for the first 1 km = $2.80
Remaining distance to pay for
= 4.3 - 1
= 3.3 km
1 km = 1000 m
3.3 km = 3.3 x 1000 = 3300 m
Sets of additional 300 m
= 3300 ÷ 300
= 11 r 0
Amount to pay for remaining 3.3 km
= 11 x 0.21
= $2.31
1 min = 60 s
3 min = 3 x 60 = 180 s
Sets of 40 seconds of waiting
= 180 ÷ 40
= 4 r 20
Sets of 40 seconds of waiting or less
= 4 + 1
= 5
Amount to pay for sets of 40 seconds of waiting or less
= 5 x 0.30
= $1.50
Sarah's taxi fare
= 2.80 + 2.31 + 1.50
= $6.61
Answer(s): $6.61
