- Howard parked his car at the carpark at 7.00 p.m. for 1 hour and 41 minutes. How much did he have to pay?
- Min parked her car at the car park from 4:35 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Howard had to pay for 1 hour and 41 minutes
= 2.70 + 2.40 + 2.40
= $7.50
(b)
1 h = 60 min
From 4:35 p.m. to 5:35 p.m.:
1 h
Amount that Min had to pay from 4:35 p.m. to 5:35 p.m = $2.70
From 5:35 p.m. to 10:00 p.m.: 4 h 25 min
4 h 25 min = 4 x 60 + 25 = 265 min
Number of sets of additional 30 minutes in 4 h 25 min
= 265 ÷ 30
= 8 r 25
Number of sets of additional 30 minutes that Min had to pay for
= 8 + 1
= 9
Amount that Min had to pay for all the additional 30 minutes or part thereof for 4 h 25 min
= 9 x 2.40
= $21.60
From 10:00 p.m. to 6.30. a.m.
Amount that Min had to pay from 10:00 to 6.30 a.m. = $6
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Min had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 2.40
= $21.60
Total amount that Min had to pay
= 2.70 + 21.60 + 6 + 21.60
= $51.90
Answer(s): (a) $7.50; (b) $51.90
