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 3 minutes and travelled a total distance of 6.3 km to reach Fiona's home. How much was her taxi fare?

Taxi Fare
First km	$3.90
Every additional 400 m or less	$0.21
Every 45 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.90

Remaining distance to pay for
= 6.3 - 1
= 5.3 km

1 km = 1000 m
5.3 km = 5.3 x 1000 = 5300 m

Sets of additional 400 m
= 5300 ÷ 400
= 13 r 100

Sets of additional 400 m or less
= 13 + 1
= 14

Amount to pay for remaining 5.3 km
= 14 x 0.21
= $2.94

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 45 seconds of waiting
= 180 ÷ 45
= 4 r 0

Amount to pay for sets of 45 seconds of waiting or less
= 4 x 0.30
= $1.20

Fiona's taxi fare
= 3.90 + 2.94 + 1.20
= $8.04

Answer(s): $8.04
