Cole parked his car at the carpark from 1.42 p.m to 7 p.m. How much did he pay for his parking?
From 1.42 p.m. to 2.42 p.m.: 1 h
From 2.42 p.m. to 7 p.m.: 4 h 18 min
1 h = 60 min
4 h 18 min = 4 x 60 + 18 = 258 min
Number of sets of addtional 30 min in 5 h 18 min
= 258 ÷ 30
= 8 r 18
Number of sets of 30 min that Cole had to pay for
= 8 + 1
= 9
Amount that Cole had to pay for 9 sets of additional 30 min
= 9 x 1.20
= $10.80
Total amount that Cole had to pay for his parking
= 1.80 + 10.80
= $12.60
Answer(s): $12.60
