Justin parked his car at the carpark from 1.41 p.m to 7 p.m. How much did he pay for his parking?
From 1.41 p.m. to 2.41 p.m.: 1 h
From 2.41 p.m. to 7 p.m.: 4 h 19 min
1 h = 60 min
4 h 19 min = 4 x 60 + 19 = 259 min
Number of sets of addtional 30 min in 5 h 19 min
= 259 ÷ 30
= 8 r 19
Number of sets of 30 min that Justin had to pay for
= 8 + 1
= 9
Amount that Justin had to pay for 9 sets of additional 30 min
= 9 x 1.10
= $9.90
Total amount that Justin had to pay for his parking
= 2.40 + 9.90
= $12.30
Answer(s): $12.30
