Billy parked his car at the carpark from 2.54 p.m to 8 p.m. How much did he pay for his parking?
From 2.54 p.m. to 3.54 p.m.: 1 h
From 3.54 p.m. to 8 p.m.: 4 h 6 min
1 h = 60 min
4 h 6 min = 4 x 60 + 6 = 246 min
Number of sets of addtional 30 min in 5 h 6 min
= 246 ÷ 30
= 8 r 6
Number of sets of 30 min that Billy had to pay for
= 8 + 1
= 9
Amount that Billy had to pay for 9 sets of additional 30 min
= 9 x 1.50
= $13.50
Total amount that Billy had to pay for his parking
= 2.70 + 13.50
= $16.20
Answer(s): $16.20
