Vanessa 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 6.1 km to reach Vanessa's home. How much was her taxi fare?

Taxi Fare
First km	$3.10
Every additional 400 m or less	$0.31
Every 30 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.10

Remaining distance to pay for
= 6.1 - 1
= 5.1 km

1 km = 1000 m
5.1 km = 5.1 x 1000 = 5100 m

Sets of additional 400 m
= 5100 ÷ 400
= 12 r 300

Sets of additional 400 m or less
= 12 + 1
= 13

Amount to pay for remaining 5.1 km
= 13 x 0.31
= $4.03

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.20
= $0.80

Vanessa's taxi fare
= 3.10 + 4.03 + 0.80
= $7.93

Answer(s): $7.93
