Vaidev parked his car at the carpark from 4.38 p.m to 11 p.m. How much did he pay for his parking?
From 4.38 p.m. to 5.38 p.m.: 1 h
From 5.38 p.m. to 11 p.m.: 5 h 22 min
1 h = 60 min
5 h 22 min = 5 x 60 + 22 = 322 min
Number of sets of addtional 30 min in 6 h 22 min
= 322 ÷ 30
= 10 r 22
Number of sets of 30 min that Vaidev had to pay for
= 10 + 1
= 11
Amount that Vaidev had to pay for 11 sets of additional 30 min
= 11 x 1.80
= $19.80
Total amount that Vaidev had to pay for his parking
= 2.50 + 19.80
= $22.30
Answer(s): $22.30
