- Dylan parked his car at the carpark at 3.00 p.m. for 1 hour and 29 minutes. How much did he have to pay?
- Jaslyn parked her car at the car park from 2:45 p.m. on Monday to 9 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Dylan had to pay for 1 hour and 29 minutes
= 2.70 + 1.90
= $4.60
(b)
1 h = 60 min
From 2:45 p.m. to 3:45 p.m.:
1 h
Amount that Jaslyn had to pay from 2:45 p.m. to 3:45 p.m = $2.70
From 3:45 p.m. to 10:00 p.m.: 6 h 15 min
6 h 15 min = 6 x 60 + 15 = 375 min
Number of sets of additional 30 minutes in 6 h 15 min
= 375 ÷ 30
= 12 r 15
Number of sets of additional 30 minutes that Jaslyn had to pay for
= 12 + 1
= 13
Amount that Jaslyn had to pay for all the additional 30 minutes or part thereof for 6 h 15 min
= 13 x 1.90
= $24.70
From 10:00 p.m. to 6.30. a.m.
Amount that Jaslyn had to pay from 10:00 to 6.30 a.m. = $11
From 6.30 a.m. to 9 a.m.: 2 h 30 min
2 h 30 min = 2 x 60 + 30 = 150 min
Number of sets of additional 30 minutes in 2 h 30 min
= 150 ÷ 30
= 5
Amount that Jaslyn had to pay for all the additional 30 minutes or part thereof for 2 h 30 min
= 5 x 1.90
= $9.50
Total amount that Jaslyn had to pay
= 2.70 + 24.70 + 11 + 9.50
= $47.90
Answer(s): (a) $4.60; (b) $47.90
