- Jenson parked his car at the carpark at 5.00 p.m. for 1 hour and 56 minutes. How much did he have to pay?
- Xuan parked her car at the car park from 6:40 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Jenson had to pay for 1 hour and 56 minutes
= 2.40 + 2.10 + 2.10
= $6.60
(b)
1 h = 60 min
From 6:40 p.m. to 7:40 p.m.:
1 h
Amount that Xuan had to pay from 6:40 p.m. to 7:40 p.m = $2.40
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 Xuan had to pay for
= 4 + 1
= 5
Amount that Xuan had to pay for all the additional 30 minutes or part thereof for 2 h 20 min
= 5 x 2.10
= $10.50
From 10:00 p.m. to 6.30. a.m.
Amount that Xuan had to pay from 10:00 to 6.30 a.m. = $5
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Xuan had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 2.10
= $18.90
Total amount that Xuan had to pay
= 2.40 + 10.50 + 5 + 18.90
= $36.80
Answer(s): (a) $6.60; (b) $36.80
