Riordan parked his car at the carpark from 1.54 p.m to 6 p.m. How much did he pay for his parking?
From 1.54 p.m. to 2.54 p.m.: 1 h
From 2.54 p.m. to 6 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 Riordan had to pay for
= 6 + 1
= 7
Amount that Riordan had to pay for 7 sets of additional 30 min
= 7 x 1.20
= $8.40
Total amount that Riordan had to pay for his parking
= 2.00 + 8.40
= $10.40
Answer(s): $10.40
