Ian parked his car at the carpark from 3.34 p.m to 11 p.m. How much did he pay for his parking?
From 3.34 p.m. to 4.34 p.m.: 1 h
From 4.34 p.m. to 11 p.m.: 6 h 26 min
1 h = 60 min
6 h 26 min = 6 x 60 + 26 = 386 min
Number of sets of addtional 30 min in 7 h 26 min
= 386 ÷ 30
= 12 r 26
Number of sets of 30 min that Ian had to pay for
= 12 + 1
= 13
Amount that Ian had to pay for 13 sets of additional 30 min
= 13 x 1.90
= $24.70
Total amount that Ian had to pay for his parking
= 3.10 + 24.70
= $27.80
Answer(s): $27.80
