Usha 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 8.2 km to reach Usha's home. How much was her taxi fare?

Taxi Fare
First km	$3.50
Every additional 300 m or less	$0.35
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.50

Remaining distance to pay for
= 8.2 - 1
= 7.2 km

1 km = 1000 m
7.2 km = 7.2 x 1000 = 7200 m

Sets of additional 300 m
= 7200 ÷ 300
= 24 r 0

Amount to pay for remaining 7.2 km
= 24 x 0.35
= $8.40

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 35 seconds of waiting
= 180 ÷ 35
= 5 r 5

Sets of 35 seconds of waiting or less
= 5 + 1
= 6

Amount to pay for sets of 35 seconds of waiting or less
= 6 x 0.20
= $1.20

Usha's taxi fare
= 3.50 + 8.40 + 1.20
= $13.10

Answer(s): $13.10
