Ken parked his car at the carpark from 2.36 p.m to 9 p.m. How much did he pay for his parking?
From 2.36 p.m. to 3.36 p.m.: 1 h
From 3.36 p.m. to 9 p.m.: 5 h 24 min
1 h = 60 min
5 h 24 min = 5 x 60 + 24 = 324 min
Number of sets of addtional 30 min in 6 h 24 min
= 324 ÷ 30
= 10 r 24
Number of sets of 30 min that Ken had to pay for
= 10 + 1
= 11
Amount that Ken had to pay for 11 sets of additional 30 min
= 11 x 1.90
= $20.90
Total amount that Ken had to pay for his parking
= 2.40 + 20.90
= $23.30
Answer(s): $23.30
