Flynn parked his car at the carpark from 2.51 p.m to 9 p.m. How much did he pay for his parking?
From 2.51 p.m. to 3.51 p.m.: 1 h
From 3.51 p.m. to 9 p.m.: 5 h 9 min
1 h = 60 min
5 h 9 min = 5 x 60 + 9 = 309 min
Number of sets of addtional 30 min in 6 h 9 min
= 309 ÷ 30
= 10 r 9
Number of sets of 30 min that Flynn had to pay for
= 10 + 1
= 11
Amount that Flynn had to pay for 11 sets of additional 30 min
= 11 x 1.70
= $18.70
Total amount that Flynn had to pay for his parking
= 2.50 + 18.70
= $21.20
Answer(s): $21.20
