Riordan parked his car at the carpark from 1.59 p.m to 6 p.m. How much did he pay for his parking?
From 1.59 p.m. to 2.59 p.m.: 1 h
From 2.59 p.m. to 6 p.m.: 3 h 1 min
1 h = 60 min
3 h 1 min = 3 x 60 + 1 = 181 min
Number of sets of addtional 30 min in 4 h 1 min
= 181 ÷ 30
= 6 r 1
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 1.70
= $11.90
Total amount that Riordan had to pay for his parking
= 2.50 + 11.90
= $14.40
Answer(s): $14.40
