Ian parked his car at the carpark from 6.39 p.m to 9 p.m. How much did he pay for his parking?
From 6.39 p.m. to 7.39 p.m.: 1 h
From 7.39 p.m. to 9 p.m.: 1 h 21 min
1 h = 60 min
1 h 21 min = 1 x 60 + 21 = 81 min
Number of sets of addtional 30 min in 2 h 21 min
= 81 ÷ 30
= 2 r 21
Number of sets of 30 min that Ian had to pay for
= 2 + 1
= 3
Amount that Ian had to pay for 3 sets of additional 30 min
= 3 x 1.90
= $5.70
Total amount that Ian had to pay for his parking
= 2.80 + 5.70
= $8.50
Answer(s): $8.50
