Ivory 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 6.4 km to reach Ivory's home. How much was her taxi fare?

Taxi Fare
First km	$2.20
Every additional 500 m or less	$0.24
Every 45 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.20

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 500 m
= 5400 ÷ 500
= 10 r 400

Sets of additional 500 m or less
= 10 + 1
= 11

Amount to pay for remaining 5.4 km
= 11 x 0.24
= $2.64

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 0.20
= $0.80

Ivory's taxi fare
= 2.20 + 2.64 + 0.80
= $5.64

Answer(s): $5.64
