Taxi Fare |
|
First km |
$2.80 |
Every additional 500 m or less |
$0.41 |
Every 35 seconds waiting or less |
$0.40 |
Amount to pay for the first 1 km = $2.80
Remaining distance to pay for
= 9.7 - 1
= 8.7 km
1 km = 1000 m
8.7 km = 8.7 x 1000 = 8700 m
Sets of additional 500 m
= 8700 ÷ 500
= 17 r 200
Sets of additional 500 m or less
= 17 + 1
= 18
Amount to pay for remaining 8.7 km
= 18 x 0.41
= $7.38
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 0.40
= $1.60
Rachel's taxi fare
= 2.80 + 7.38 + 1.60
= $11.78
Answer(s): $11.78
