Paul parked his car at the carpark from 4.57 p.m to 10 p.m. How much did he pay for his parking?
From 4.57 p.m. to 5.57 p.m.: 1 h
From 5.57 p.m. to 10 p.m.: 4 h 3 min
1 h = 60 min
4 h 3 min = 4 x 60 + 3 = 243 min
Number of sets of addtional 30 min in 5 h 3 min
= 243 ÷ 30
= 8 r 3
Number of sets of 30 min that Paul had to pay for
= 8 + 1
= 9
Amount that Paul had to pay for 9 sets of additional 30 min
= 9 x 1.60
= $14.40
Total amount that Paul had to pay for his parking
= 3.10 + 14.40
= $17.50
Answer(s): $17.50
