Wesley parked his car at the carpark from 1.38 p.m to 7 p.m. How much did he pay for his parking?
From 1.38 p.m. to 2.38 p.m.: 1 h
From 2.38 p.m. to 7 p.m.: 4 h 22 min
1 h = 60 min
4 h 22 min = 4 x 60 + 22 = 262 min
Number of sets of addtional 30 min in 5 h 22 min
= 262 ÷ 30
= 8 r 22
Number of sets of 30 min that Wesley had to pay for
= 8 + 1
= 9
Amount that Wesley had to pay for 9 sets of additional 30 min
= 9 x 1.90
= $17.10
Total amount that Wesley had to pay for his parking
= 3.20 + 17.10
= $20.30
Answer(s): $20.30
