Oliver parked his car at the carpark from 1.55 p.m to 9 p.m. How much did he pay for his parking?
From 1.55 p.m. to 2.55 p.m.: 1 h
From 2.55 p.m. to 9 p.m.: 6 h 5 min
1 h = 60 min
6 h 5 min = 6 x 60 + 5 = 365 min
Number of sets of addtional 30 min in 7 h 5 min
= 365 ÷ 30
= 12 r 5
Number of sets of 30 min that Oliver had to pay for
= 12 + 1
= 13
Amount that Oliver had to pay for 13 sets of additional 30 min
= 13 x 1.50
= $19.50
Total amount that Oliver had to pay for his parking
= 3.00 + 19.50
= $22.50
Answer(s): $22.50
