- Zeph parked his car at the carpark at 11.00 a.m. for 1 hour and 12 minutes. How much did he have to pay?
- Zoe parked her car at the car park from 4:45 p.m. on Monday to 9 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Zeph had to pay for 1 hour and 12 minutes
= 2.40 + 1.50
= $3.90
(b)
1 h = 60 min
From 4:45 p.m. to 5:45 p.m.:
1 h
Amount that Zoe had to pay from 4:45 p.m. to 5:45 p.m = $2.40
From 5:45 p.m. to 10:00 p.m.: 4 h 15 min
4 h 15 min = 4 x 60 + 15 = 255 min
Number of sets of additional 30 minutes in 4 h 15 min
= 255 ÷ 30
= 8 r 15
Number of sets of additional 30 minutes that Zoe had to pay for
= 8 + 1
= 9
Amount that Zoe had to pay for all the additional 30 minutes or part thereof for 4 h 15 min
= 9 x 1.50
= $13.50
From 10:00 p.m. to 6.30. a.m.
Amount that Zoe had to pay from 10:00 to 6.30 a.m. = $11
From 6.30 a.m. to 9 a.m.: 2 h 30 min
2 h 30 min = 2 x 60 + 30 = 150 min
Number of sets of additional 30 minutes in 2 h 30 min
= 150 ÷ 30
= 5
Amount that Zoe had to pay for all the additional 30 minutes or part thereof for 2 h 30 min
= 5 x 1.50
= $7.50
Total amount that Zoe had to pay
= 2.40 + 13.50 + 11 + 7.50
= $34.40
Answer(s): (a) $3.90; (b) $34.40
