Fiona 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 8.9 km to reach Fiona's home. How much was her taxi fare?

Taxi Fare
First km	$3.40
Every additional 400 m or less	$0.44
Every 30 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.40

Remaining distance to pay for
= 8.9 - 1
= 7.9 km

1 km = 1000 m
7.9 km = 7.9 x 1000 = 7900 m

Sets of additional 400 m
= 7900 ÷ 400
= 19 r 300

Sets of additional 400 m or less
= 19 + 1
= 20

Amount to pay for remaining 7.9 km
= 20 x 0.44
= $8.80

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.40
= $1.60

Fiona's taxi fare
= 3.40 + 8.80 + 1.60
= $13.80

Answer(s): $13.80
