Olivia 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 6.3 km to reach Olivia's home. How much was her taxi fare?

Taxi Fare
First km	$2.40
Every additional 400 m or less	$0.38
Every 45 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.40

Remaining distance to pay for
= 6.3 - 1
= 5.3 km

1 km = 1000 m
5.3 km = 5.3 x 1000 = 5300 m

Sets of additional 400 m
= 5300 ÷ 400
= 13 r 100

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

Amount to pay for remaining 5.3 km
= 14 x 0.38
= $5.32

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 45 seconds of waiting
= 120 ÷ 45
= 2 r 30

Sets of 45 seconds of waiting or less
= 2 + 1
= 3

Amount to pay for sets of 45 seconds of waiting or less
= 3 x 0.20
= $0.60

Olivia's taxi fare
= 2.40 + 5.32 + 0.60
= $8.32

Answer(s): $8.32
