PSLE Mary 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 4.6 km to reach Mary's home. How much was her taxi fare?
Taxi Fare |
|
First km |
$3.30 |
Every additional 400 m or less |
$0.23 |
Every 40 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.30
Remaining distance to pay for
= 4.6 - 1
= 3.6 km
1 km = 1000 m
3.6 km = 3.6 x 1000 = 3600 m
Sets of additional 400 m
= 3600 ÷ 400
= 9 r 0
Amount to pay for remaining 3.6 km
= 9 x 0.23
= $2.07
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 0.20
= $1.00
Mary's taxi fare
= 3.30 + 2.07 + 1.00
= $6.37
Answer(s): $6.37
