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 3 minutes and travelled a total distance of 6.9 km to reach Zara's home. How much was her taxi fare?

Taxi Fare
First km	$3.30
Every additional 500 m or less	$0.42
Every 45 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.30

Remaining distance to pay for
= 6.9 - 1
= 5.9 km

1 km = 1000 m
5.9 km = 5.9 x 1000 = 5900 m

Sets of additional 500 m
= 5900 ÷ 500
= 11 r 400

Sets of additional 500 m or less
= 11 + 1
= 12

Amount to pay for remaining 5.9 km
= 12 x 0.42
= $5.04

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

Zara's taxi fare
= 3.30 + 5.04 + 0.80
= $9.14

Answer(s): $9.14
