Tom parked his car at the carpark from 6.31 p.m to 11 p.m. How much did he pay for his parking?
From 6.31 p.m. to 7.31 p.m.: 1 h
From 7.31 p.m. to 11 p.m.: 3 h 29 min
1 h = 60 min
3 h 29 min = 3 x 60 + 29 = 209 min
Number of sets of addtional 30 min in 4 h 29 min
= 209 ÷ 30
= 6 r 29
Number of sets of 30 min that Tom had to pay for
= 6 + 1
= 7
Amount that Tom had to pay for 7 sets of additional 30 min
= 7 x 1.70
= $11.90
Total amount that Tom had to pay for his parking
= 2.40 + 11.90
= $14.30
Answer(s): $14.30
