Oliver parked his car at the carpark from 2.37 p.m to 9 p.m. How much did he pay for his parking?
From 2.37 p.m. to 3.37 p.m.: 1 h
From 3.37 p.m. to 9 p.m.: 5 h 23 min
1 h = 60 min
5 h 23 min = 5 x 60 + 23 = 323 min
Number of sets of addtional 30 min in 6 h 23 min
= 323 ÷ 30
= 10 r 23
Number of sets of 30 min that Oliver had to pay for
= 10 + 1
= 11
Amount that Oliver had to pay for 11 sets of additional 30 min
= 11 x 1.60
= $17.60
Total amount that Oliver had to pay for his parking
= 2.90 + 17.60
= $20.50
Answer(s): $20.50
