Nora 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 4.5 km to reach Nora's home. How much was her taxi fare?

Taxi Fare
First km	$2.40
Every additional 300 m or less	$0.33
Every 45 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.40

Remaining distance to pay for
= 4.5 - 1
= 3.5 km

1 km = 1000 m
3.5 km = 3.5 x 1000 = 3500 m

Sets of additional 300 m
= 3500 ÷ 300
= 11 r 200

Sets of additional 300 m or less
= 11 + 1
= 12

Amount to pay for remaining 3.5 km
= 12 x 0.33
= $3.96

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

Nora's taxi fare
= 2.40 + 3.96 + 0.80
= $7.16

Answer(s): $7.16
