After the second hour |
$1.30 per 12 hour or part thereof |
Emma paid $10.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Emma paid for the first 2 hours = $8.00
Amount that Emma paid after the second hour
= 10.60 - 8.00
= $2.60
Number of sets of $1.30
= 2.60 ÷ 1.30
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Emma parked her car at the carpark
= 2 + 1
= 3 h
Answer(s): 3 h
