Howard parked his car at the carpark from 2.37 p.m to 7 p.m. How much did he pay for his parking?
From 2.37 p.m. to 3.37 p.m.: 1 h
From 3.37 p.m. to 7 p.m.: 3 h 23 min
1 h = 60 min
3 h 23 min = 3 x 60 + 23 = 203 min
Number of sets of addtional 30 min in 4 h 23 min
= 203 ÷ 30
= 6 r 23
Number of sets of 30 min that Howard had to pay for
= 6 + 1
= 7
Amount that Howard had to pay for 7 sets of additional 30 min
= 7 x 1.10
= $7.70
Total amount that Howard had to pay for his parking
= 2.50 + 7.70
= $10.20
Answer(s): $10.20
