Billy parked his car at the carpark from 4.43 p.m to 11 p.m. How much did he pay for his parking?
From 4.43 p.m. to 5.43 p.m.: 1 h
From 5.43 p.m. to 11 p.m.: 5 h 17 min
1 h = 60 min
5 h 17 min = 5 x 60 + 17 = 317 min
Number of sets of addtional 30 min in 6 h 17 min
= 317 ÷ 30
= 10 r 17
Number of sets of 30 min that Billy had to pay for
= 10 + 1
= 11
Amount that Billy had to pay for 11 sets of additional 30 min
= 11 x 1.70
= $18.70
Total amount that Billy had to pay for his parking
= 3.00 + 18.70
= $21.70
Answer(s): $21.70
