Riordan parked his car at the carpark from 3.36 p.m to 9 p.m. How much did he pay for his parking?
From 3.36 p.m. to 4.36 p.m.: 1 h
From 4.36 p.m. to 9 p.m.: 4 h 24 min
1 h = 60 min
4 h 24 min = 4 x 60 + 24 = 264 min
Number of sets of addtional 30 min in 5 h 24 min
= 264 ÷ 30
= 8 r 24
Number of sets of 30 min that Riordan had to pay for
= 8 + 1
= 9
Amount that Riordan had to pay for 9 sets of additional 30 min
= 9 x 1.40
= $12.60
Total amount that Riordan had to pay for his parking
= 2.50 + 12.60
= $15.10
Answer(s): $15.10
