Raeann 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 7.8 km to reach Raeann's home. How much was her taxi fare?

Taxi Fare
First km	$3.10
Every additional 400 m or less	$0.44
Every 45 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.10

Remaining distance to pay for
= 7.8 - 1
= 6.8 km

1 km = 1000 m
6.8 km = 6.8 x 1000 = 6800 m

Sets of additional 400 m
= 6800 ÷ 400
= 17 r 0

Amount to pay for remaining 6.8 km
= 17 x 0.44
= $7.48

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 0.30
= $0.90

Raeann's taxi fare
= 3.10 + 7.48 + 0.90
= $11.48

Answer(s): $11.48
