- Wesley parked his car at the carpark at 5.00 p.m. for 1 hour and 53 minutes. How much did he have to pay?
- Penelope parked her car at the car park from 1:10 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Wesley had to pay for 1 hour and 53 minutes
= 1.60 + 0.80 + 0.80
= $3.20
(b)
1 h = 60 min
From 1:10 p.m. to 2:10 p.m.:
1 h
Amount that Penelope had to pay from 1:10 p.m. to 2:10 p.m = $1.60
From 2:10 p.m. to 10:00 p.m.: 7 h 50 min
7 h 50 min = 7 x 60 + 50 = 470 min
Number of sets of additional 30 minutes in 7 h 50 min
= 470 ÷ 30
= 15 r 20
Number of sets of additional 30 minutes that Penelope had to pay for
= 15 + 1
= 16
Amount that Penelope had to pay for all the additional 30 minutes or part thereof for 7 h 50 min
= 16 x 0.80
= $12.80
From 10:00 p.m. to 6.30. a.m.
Amount that Penelope 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 Penelope had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 0.80
= $2.40
Total amount that Penelope had to pay
= 1.60 + 12.80 + 5 + 2.40
= $21.80
Answer(s): (a) $3.20; (b) $21.80
