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

Taxi Fare
First km	$2.40
Every additional 500 m or less	$0.37
Every 45 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $2.40

Remaining distance to pay for
= 8.5 - 1
= 7.5 km

1 km = 1000 m
7.5 km = 7.5 x 1000 = 7500 m

Sets of additional 500 m
= 7500 ÷ 500
= 15 r 0

Amount to pay for remaining 7.5 km
= 15 x 0.37
= $5.55

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 0.40
= $1.20

Olivia's taxi fare
= 2.40 + 5.55 + 1.20
= $9.15

Answer(s): $9.15
