- George parked his car at the carpark at 6.00 p.m. for 1 hour and 17 minutes. How much did he have to pay?
- Raeann parked her car at the car park from 4:50 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that George had to pay for 1 hour and 17 minutes
= 2.60 + 1.80
= $4.40
(b)
1 h = 60 min
From 4:50 p.m. to 5:50 p.m.:
1 h
Amount that Raeann had to pay from 4:50 p.m. to 5:50 p.m = $2.60
From 5:50 p.m. to 10:00 p.m.: 4 h 10 min
4 h 10 min = 4 x 60 + 10 = 250 min
Number of sets of additional 30 minutes in 4 h 10 min
= 250 ÷ 30
= 8 r 10
Number of sets of additional 30 minutes that Raeann had to pay for
= 8 + 1
= 9
Amount that Raeann had to pay for all the additional 30 minutes or part thereof for 4 h 10 min
= 9 x 1.80
= $16.20
From 10:00 p.m. to 6.30. a.m.
Amount that Raeann had to pay from 10:00 to 6.30 a.m. = $10
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 Raeann had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.80
= $5.40
Total amount that Raeann had to pay
= 2.60 + 16.20 + 10 + 5.40
= $34.20
Answer(s): (a) $4.40; (b) $34.20
