Valen parked his car at the carpark from 3.48 p.m to 10 p.m. How much did he pay for his parking?
From 3.48 p.m. to 4.48 p.m.: 1 h
From 4.48 p.m. to 10 p.m.: 5 h 12 min
1 h = 60 min
5 h 12 min = 5 x 60 + 12 = 312 min
Number of sets of addtional 30 min in 6 h 12 min
= 312 ÷ 30
= 10 r 12
Number of sets of 30 min that Valen had to pay for
= 10 + 1
= 11
Amount that Valen had to pay for 11 sets of additional 30 min
= 11 x 1.70
= $18.70
Total amount that Valen had to pay for his parking
= 2.40 + 18.70
= $21.10
Answer(s): $21.10
