Barbara 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 4.8 km to reach Barbara's home. How much was her taxi fare?

Taxi Fare
First km	$3.40
Every additional 300 m or less	$0.36
Every 30 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.40

Remaining distance to pay for
= 4.8 - 1
= 3.8 km

1 km = 1000 m
3.8 km = 3.8 x 1000 = 3800 m

Sets of additional 300 m
= 3800 ÷ 300
= 12 r 200

Sets of additional 300 m or less
= 12 + 1
= 13

Amount to pay for remaining 3.8 km
= 13 x 0.36
= $4.68

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 30 seconds of waiting
= 180 ÷ 30
= 6 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 6 x 0.30
= $1.80

Barbara's taxi fare
= 3.40 + 4.68 + 1.80
= $9.88

Answer(s): $9.88
