Paul parked his car at the carpark from 1.51 p.m to 6 p.m. How much did he pay for his parking?
From 1.51 p.m. to 2.51 p.m.: 1 h
From 2.51 p.m. to 6 p.m.: 3 h 9 min
1 h = 60 min
3 h 9 min = 3 x 60 + 9 = 189 min
Number of sets of addtional 30 min in 4 h 9 min
= 189 ÷ 30
= 6 r 9
Number of sets of 30 min that Paul had to pay for
= 6 + 1
= 7
Amount that Paul had to pay for 7 sets of additional 30 min
= 7 x 1.90
= $13.30
Total amount that Paul had to pay for his parking
= 3.30 + 13.30
= $16.60
Answer(s): $16.60
