- Bryan parked his car at the carpark at 2.00 p.m. for 1 hour and 18 minutes. How much did he have to pay?
- Shiyun parked her car at the car park from 1:25 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Bryan had to pay for 1 hour and 18 minutes
= 1.80 + 1.10
= $2.90
(b)
1 h = 60 min
From 1:25 p.m. to 2:25 p.m.:
1 h
Amount that Shiyun had to pay from 1:25 p.m. to 2:25 p.m = $1.80
From 2:25 p.m. to 10:00 p.m.: 7 h 35 min
7 h 35 min = 7 x 60 + 35 = 455 min
Number of sets of additional 30 minutes in 7 h 35 min
= 455 ÷ 30
= 15 r 5
Number of sets of additional 30 minutes that Shiyun had to pay for
= 15 + 1
= 16
Amount that Shiyun had to pay for all the additional 30 minutes or part thereof for 7 h 35 min
= 16 x 1.10
= $17.60
From 10:00 p.m. to 6.30. a.m.
Amount that Shiyun had to pay from 10:00 to 6.30 a.m. = $8
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 1.10
= $7.70
Total amount that Shiyun had to pay
= 1.80 + 17.60 + 8 + 7.70
= $35.10
Answer(s): (a) $2.90; (b) $35.10
