Tim parked his car at the carpark from 3.49 p.m to 11 p.m. How much did he pay for his parking?
From 3.49 p.m. to 4.49 p.m.: 1 h
From 4.49 p.m. to 11 p.m.: 6 h 11 min
1 h = 60 min
6 h 11 min = 6 x 60 + 11 = 371 min
Number of sets of addtional 30 min in 7 h 11 min
= 371 ÷ 30
= 12 r 11
Number of sets of 30 min that Tim had to pay for
= 12 + 1
= 13
Amount that Tim had to pay for 13 sets of additional 30 min
= 13 x 1.20
= $15.60
Total amount that Tim had to pay for his parking
= 2.10 + 15.60
= $17.70
Answer(s): $17.70
