Archie parked his car at the carpark from 3.40 p.m to 8 p.m. How much did he pay for his parking?
From 3.40 p.m. to 4.40 p.m.: 1 h
From 4.40 p.m. to 8 p.m.: 3 h 20 min
1 h = 60 min
3 h 20 min = 3 x 60 + 20 = 200 min
Number of sets of addtional 30 min in 4 h 20 min
= 200 ÷ 30
= 6 r 20
Number of sets of 30 min that Archie had to pay for
= 6 + 1
= 7
Amount that Archie had to pay for 7 sets of additional 30 min
= 7 x 1.50
= $10.50
Total amount that Archie had to pay for his parking
= 2.30 + 10.50
= $12.80
Answer(s): $12.80
