Howard parked his car at the carpark from 4.54 p.m to 9 p.m. How much did he pay for his parking?
From 4.54 p.m. to 5.54 p.m.: 1 h
From 5.54 p.m. to 9 p.m.: 3 h 6 min
1 h = 60 min
3 h 6 min = 3 x 60 + 6 = 186 min
Number of sets of addtional 30 min in 4 h 6 min
= 186 ÷ 30
= 6 r 6
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 1.70
= $11.90
Total amount that Howard had to pay for his parking
= 3.20 + 11.90
= $15.10
Answer(s): $15.10
