Zara 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 9.1 km to reach Zara's home. How much was her taxi fare?

Taxi Fare
First km	$3.40
Every additional 400 m or less	$0.26
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.40

Remaining distance to pay for
= 9.1 - 1
= 8.1 km

1 km = 1000 m
8.1 km = 8.1 x 1000 = 8100 m

Sets of additional 400 m
= 8100 ÷ 400
= 20 r 100

Sets of additional 400 m or less
= 20 + 1
= 21

Amount to pay for remaining 8.1 km
= 21 x 0.26
= $5.46

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15

Sets of 35 seconds of waiting or less
= 3 + 1
= 4

Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.20
= $0.80

Zara's taxi fare
= 3.40 + 5.46 + 0.80
= $9.66

Answer(s): $9.66
