- Elijah parked his car at the carpark at 4.00 p.m. for 1 hour and 25 minutes. How much did he have to pay?
- Min parked her car at the car park from 5:50 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Elijah had to pay for 1 hour and 25 minutes
= 1.90 + 1.30
= $3.20
(b)
1 h = 60 min
From 5:50 p.m. to 6:50 p.m.:
1 h
Amount that Min had to pay from 5:50 p.m. to 6:50 p.m = $1.90
From 6:50 p.m. to 10:00 p.m.: 3 h 10 min
3 h 10 min = 3 x 60 + 10 = 190 min
Number of sets of additional 30 minutes in 3 h 10 min
= 190 ÷ 30
= 6 r 10
Number of sets of additional 30 minutes that Min had to pay for
= 6 + 1
= 7
Amount that Min had to pay for all the additional 30 minutes or part thereof for 3 h 10 min
= 7 x 1.30
= $9.10
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 1.30
= $11.70
Total amount that Min had to pay
= 1.90 + 9.10 + 6 + 11.70
= $28.70
Answer(s): (a) $3.20; (b) $28.70
