Hilda 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 8.7 km to reach Hilda's home. How much was her taxi fare?

Taxi Fare
First km	$2.40
Every additional 400 m or less	$0.41
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.40

Remaining distance to pay for
= 8.7 - 1
= 7.7 km

1 km = 1000 m
7.7 km = 7.7 x 1000 = 7700 m

Sets of additional 400 m
= 7700 ÷ 400
= 19 r 100

Sets of additional 400 m or less
= 19 + 1
= 20

Amount to pay for remaining 7.7 km
= 20 x 0.41
= $8.20

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15

Sets of 35 seconds of waiting or less
= 3 + 1
= 4

Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.20
= $0.80

Hilda's taxi fare
= 2.40 + 8.20 + 0.80
= $11.40

Answer(s): $11.40
