- Vincent parked his car at the carpark at 11.00 a.m. for 1 hour and 29 minutes. How much did he have to pay?
- Gillian parked her car at the car park from 6:40 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Vincent had to pay for 1 hour and 29 minutes
= 2.80 + 2.30
= $5.10
(b)
1 h = 60 min
From 6:40 p.m. to 7:40 p.m.:
1 h
Amount that Gillian had to pay from 6:40 p.m. to 7:40 p.m = $2.80
From 7:40 p.m. to 10:00 p.m.: 2 h 20 min
2 h 20 min = 2 x 60 + 20 = 140 min
Number of sets of additional 30 minutes in 2 h 20 min
= 140 ÷ 30
= 4 r 20
Number of sets of additional 30 minutes that Gillian had to pay for
= 4 + 1
= 5
Amount that Gillian had to pay for all the additional 30 minutes or part thereof for 2 h 20 min
= 5 x 2.30
= $11.50
From 10:00 p.m. to 6.30. a.m.
Amount that Gillian had to pay from 10:00 to 6.30 a.m. = $7
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 2.30
= $6.90
Total amount that Gillian had to pay
= 2.80 + 11.50 + 7 + 6.90
= $28.20
Answer(s): (a) $5.10; (b) $28.20
