- Vaidev parked his car at the carpark at 1.00 p.m. for 1 hour and 9 minutes. How much did he have to pay?
- Wendy parked her car at the car park from 6:15 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Vaidev had to pay for 1 hour and 9 minutes
= 2.70 + 2.20
= $4.90
(b)
1 h = 60 min
From 6:15 p.m. to 7:15 p.m.:
1 h
Amount that Wendy had to pay from 6:15 p.m. to 7:15 p.m = $2.70
From 7:15 p.m. to 10:00 p.m.: 2 h 45 min
2 h 45 min = 2 x 60 + 45 = 165 min
Number of sets of additional 30 minutes in 2 h 45 min
= 165 ÷ 30
= 5 r 15
Number of sets of additional 30 minutes that Wendy had to pay for
= 5 + 1
= 6
Amount that Wendy had to pay for all the additional 30 minutes or part thereof for 2 h 45 min
= 6 x 2.20
= $13.20
From 10:00 p.m. to 6.30. a.m.
Amount that Wendy had to pay from 10:00 to 6.30 a.m. = $11
From 6.30 a.m. to 10 a.m.: 3 h 30 min
3 h 30 min = 3 x 60 + 30 = 210 min
Number of sets of additional 30 minutes in 3 h 30 min
= 210 ÷ 30
= 7
Amount that Wendy had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 2.20
= $15.40
Total amount that Wendy had to pay
= 2.70 + 13.20 + 11 + 15.40
= $42.30
Answer(s): (a) $4.90; (b) $42.30
