Ken parked his car at the carpark from 1.37 p.m to 4 p.m. How much did he pay for his parking?
From 1.37 p.m. to 2.37 p.m.: 1 h
From 2.37 p.m. to 4 p.m.: 1 h 23 min
1 h = 60 min
1 h 23 min = 1 x 60 + 23 = 83 min
Number of sets of addtional 30 min in 2 h 23 min
= 83 ÷ 30
= 2 r 23
Number of sets of 30 min that Ken had to pay for
= 2 + 1
= 3
Amount that Ken had to pay for 3 sets of additional 30 min
= 3 x 1.40
= $4.20
Total amount that Ken had to pay for his parking
= 2.50 + 4.20
= $6.70
Answer(s): $6.70
