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

Taxi Fare
First km	$2.90
Every additional 300 m or less	$0.28
Every 40 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $2.90

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 300 m
= 3800 ÷ 300
= 12 r 200

Sets of additional 300 m or less
= 12 + 1
= 13

Amount to pay for remaining 3.8 km
= 13 x 0.28
= $3.64

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 40 seconds of waiting
= 120 ÷ 40
= 3 r 0

Amount to pay for sets of 40 seconds of waiting or less
= 3 x 0.30
= $0.90

Olivia's taxi fare
= 2.90 + 3.64 + 0.90
= $7.44

Answer(s): $7.44
