Riordan parked his car at the carpark from 3.35 p.m to 6 p.m. How much did he pay for his parking?
From 3.35 p.m. to 4.35 p.m.: 1 h
From 4.35 p.m. to 6 p.m.: 1 h 25 min
1 h = 60 min
1 h 25 min = 1 x 60 + 25 = 85 min
Number of sets of addtional 30 min in 2 h 25 min
= 85 ÷ 30
= 2 r 25
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 1.60
= $4.80
Total amount that Riordan had to pay for his parking
= 3.10 + 4.80
= $7.90
Answer(s): $7.90
