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

Taxi Fare
First km	$2.80
Every additional 500 m or less	$0.32
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.80

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 500 m
= 3800 ÷ 500
= 7 r 300

Sets of additional 500 m or less
= 7 + 1
= 8

Amount to pay for remaining 3.8 km
= 8 x 0.32
= $2.56

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

Zoe's taxi fare
= 2.80 + 2.56 + 0.80
= $6.16

Answer(s): $6.16
