Billy parked his car at the carpark from 2.31 p.m to 8 p.m. How much did he pay for his parking?
From 2.31 p.m. to 3.31 p.m.: 1 h
From 3.31 p.m. to 8 p.m.: 4 h 29 min
1 h = 60 min
4 h 29 min = 4 x 60 + 29 = 269 min
Number of sets of addtional 30 min in 5 h 29 min
= 269 ÷ 30
= 8 r 29
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 1.30
= $11.70
Total amount that Billy had to pay for his parking
= 2.60 + 11.70
= $14.30
Answer(s): $14.30
