Kathy 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 9.5 km to reach Kathy's home. How much was her taxi fare?

Taxi Fare
First km	$3.60
Every additional 400 m or less	$0.24
Every 45 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.60

Remaining distance to pay for
= 9.5 - 1
= 8.5 km

1 km = 1000 m
8.5 km = 8.5 x 1000 = 8500 m

Sets of additional 400 m
= 8500 ÷ 400
= 21 r 100

Sets of additional 400 m or less
= 21 + 1
= 22

Amount to pay for remaining 8.5 km
= 22 x 0.24
= $5.28

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 0.40
= $1.20

Kathy's taxi fare
= 3.60 + 5.28 + 1.20
= $10.08

Answer(s): $10.08
