Liam parked his car at the carpark from 2.50 p.m to 9 p.m. How much did he pay for his parking?
From 2.50 p.m. to 3.50 p.m.: 1 h
From 3.50 p.m. to 9 p.m.: 5 h 10 min
1 h = 60 min
5 h 10 min = 5 x 60 + 10 = 310 min
Number of sets of addtional 30 min in 6 h 10 min
= 310 ÷ 30
= 10 r 10
Number of sets of 30 min that Liam had to pay for
= 10 + 1
= 11
Amount that Liam had to pay for 11 sets of additional 30 min
= 11 x 1.40
= $15.40
Total amount that Liam had to pay for his parking
= 2.50 + 15.40
= $17.90
Answer(s): $17.90
