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 3 minutes and travelled a total distance of 5.4 km to reach Xandra's home. How much was her taxi fare?

Taxi Fare
First km	$2.10
Every additional 400 m or less	$0.44
Every 40 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $2.10

Remaining distance to pay for
= 5.4 - 1
= 4.4 km

1 km = 1000 m
4.4 km = 4.4 x 1000 = 4400 m

Sets of additional 400 m
= 4400 ÷ 400
= 11 r 0

Amount to pay for remaining 4.4 km
= 11 x 0.44
= $4.84

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 0.40
= $2.00

Xandra's taxi fare
= 2.10 + 4.84 + 2.00
= $8.94

Answer(s): $8.94
