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

Taxi Fare
First km	$2.10
Every additional 400 m or less	$0.24
Every 35 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $2.10

Remaining distance to pay for
= 6.5 - 1
= 5.5 km

1 km = 1000 m
5.5 km = 5.5 x 1000 = 5500 m

Sets of additional 400 m
= 5500 ÷ 400
= 13 r 300

Sets of additional 400 m or less
= 13 + 1
= 14

Amount to pay for remaining 5.5 km
= 14 x 0.24
= $3.36

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 0.30
= $1.80

Zara's taxi fare
= 2.10 + 3.36 + 1.80
= $7.26

Answer(s): $7.26
