David parked his car at the carpark from 1.45 p.m to 7 p.m. How much did he pay for his parking?
From 1.45 p.m. to 2.45 p.m.: 1 h
From 2.45 p.m. to 7 p.m.: 4 h 15 min
1 h = 60 min
4 h 15 min = 4 x 60 + 15 = 255 min
Number of sets of addtional 30 min in 5 h 15 min
= 255 ÷ 30
= 8 r 15
Number of sets of 30 min that David had to pay for
= 8 + 1
= 9
Amount that David had to pay for 9 sets of additional 30 min
= 9 x 1.80
= $16.20
Total amount that David had to pay for his parking
= 2.50 + 16.20
= $18.70
Answer(s): $18.70
