Henry parked his car at the carpark from 4.42 p.m to 10 p.m. How much did he pay for his parking?
From 4.42 p.m. to 5.42 p.m.: 1 h
From 5.42 p.m. to 10 p.m.: 4 h 18 min
1 h = 60 min
4 h 18 min = 4 x 60 + 18 = 258 min
Number of sets of addtional 30 min in 5 h 18 min
= 258 ÷ 30
= 8 r 18
Number of sets of 30 min that Henry had to pay for
= 8 + 1
= 9
Amount that Henry had to pay for 9 sets of additional 30 min
= 9 x 1.40
= $12.60
Total amount that Henry had to pay for his parking
= 2.90 + 12.60
= $15.50
Answer(s): $15.50
