Riordan parked his car at the carpark from 3.57 p.m to 11 p.m. How much did he pay for his parking?
From 3.57 p.m. to 4.57 p.m.: 1 h
From 4.57 p.m. to 11 p.m.: 6 h 3 min
1 h = 60 min
6 h 3 min = 6 x 60 + 3 = 363 min
Number of sets of addtional 30 min in 7 h 3 min
= 363 ÷ 30
= 12 r 3
Number of sets of 30 min that Riordan had to pay for
= 12 + 1
= 13
Amount that Riordan had to pay for 13 sets of additional 30 min
= 13 x 1.40
= $18.20
Total amount that Riordan had to pay for his parking
= 2.50 + 18.20
= $20.70
Answer(s): $20.70
