- Mark parked his car at the carpark at 11.00 a.m. for 1 hour and 44 minutes. How much did he have to pay?
- Shiyun 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 Mark had to pay for 1 hour and 44 minutes
= 1.90 + 1.60 + 1.60
= $5.10
(b)
1 h = 60 min
From 6:15 p.m. to 7:15 p.m.:
1 h
Amount that Shiyun had to pay from 6:15 p.m. to 7:15 p.m = $1.90
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 Shiyun had to pay for
= 5 + 1
= 6
Amount that Shiyun had to pay for all the additional 30 minutes or part thereof for 2 h 45 min
= 6 x 1.60
= $9.60
From 10:00 p.m. to 6.30. a.m.
Amount that Shiyun 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 Shiyun had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.60
= $11.20
Total amount that Shiyun had to pay
= 1.90 + 9.60 + 11 + 11.20
= $33.70
Answer(s): (a) $5.10; (b) $33.70
