Xandra 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 2 minutes and travelled a total distance of 6.4 km to reach Xandra's home. How much was her taxi fare?

Taxi Fare
First km	$3.40
Every additional 300 m or less	$0.43
Every 45 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.40

Remaining distance to pay for
= 6.4 - 1
= 5.4 km

1 km = 1000 m
5.4 km = 5.4 x 1000 = 5400 m

Sets of additional 300 m
= 5400 ÷ 300
= 18 r 0

Amount to pay for remaining 5.4 km
= 18 x 0.43
= $7.74

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 45 seconds of waiting
= 120 ÷ 45
= 2 r 30

Sets of 45 seconds of waiting or less
= 2 + 1
= 3

Amount to pay for sets of 45 seconds of waiting or less
= 3 x 0.30
= $0.90

Xandra's taxi fare
= 3.40 + 7.74 + 0.90
= $12.04

Answer(s): $12.04
