- Japheth parked his car at the carpark at 6.00 p.m. for 1 hour and 44 minutes. How much did he have to pay?
- Gillian parked her car at the car park from 7:50 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Japheth had to pay for 1 hour and 44 minutes
= 2.30 + 1.60 + 1.60
= $5.50
(b)
1 h = 60 min
From 7:50 p.m. to 8:50 p.m.:
1 h
Amount that Gillian had to pay from 7:50 p.m. to 8:50 p.m = $2.30
From 8:50 p.m. to 10:00 p.m.: 1 h 10 min
1 h 10 min = 1 x 60 + 10 = 70 min
Number of sets of additional 30 minutes in 1 h 10 min
= 70 ÷ 30
= 2 r 10
Number of sets of additional 30 minutes that Gillian had to pay for
= 2 + 1
= 3
Amount that Gillian had to pay for all the additional 30 minutes or part thereof for 1 h 10 min
= 3 x 1.60
= $4.80
From 10:00 p.m. to 6.30. a.m.
Amount that Gillian had to pay from 10:00 to 6.30 a.m. = $5
From 6.30 a.m. to 8 a.m.: 1 h 30 min
1 h 30 min = 1 x 60 + 30 = 90 min
Number of sets of additional 30 minutes in 1 h 30 min
= 90 ÷ 30
= 3
Amount that Gillian had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.60
= $4.80
Total amount that Gillian had to pay
= 2.30 + 4.80 + 5 + 4.80
= $16.90
Answer(s): (a) $5.50; (b) $16.90
