Riordan parked his car at the carpark from 2.51 p.m to 5 p.m. How much did he pay for his parking?
From 2.51 p.m. to 3.51 p.m.: 1 h
From 3.51 p.m. to 5 p.m.: 1 h 9 min
1 h = 60 min
1 h 9 min = 1 x 60 + 9 = 69 min
Number of sets of addtional 30 min in 2 h 9 min
= 69 ÷ 30
= 2 r 9
Number of sets of 30 min that Riordan had to pay for
= 2 + 1
= 3
Amount that Riordan had to pay for 3 sets of additional 30 min
= 3 x 1.10
= $3.30
Total amount that Riordan had to pay for his parking
= 2.50 + 3.30
= $5.80
Answer(s): $5.80
