Ethan parked his car at the carpark from 5.49 p.m to 11 p.m. How much did he pay for his parking?
From 5.49 p.m. to 6.49 p.m.: 1 h
From 6.49 p.m. to 11 p.m.: 4 h 11 min
1 h = 60 min
4 h 11 min = 4 x 60 + 11 = 251 min
Number of sets of addtional 30 min in 5 h 11 min
= 251 ÷ 30
= 8 r 11
Number of sets of 30 min that Ethan had to pay for
= 8 + 1
= 9
Amount that Ethan had to pay for 9 sets of additional 30 min
= 9 x 1.90
= $17.10
Total amount that Ethan had to pay for his parking
= 3.30 + 17.10
= $20.40
Answer(s): $20.40
