- Archie parked his car at the carpark at 8.00 p.m. for 1 hour and 54 minutes. How much did he have to pay?
- Cathy parked her car at the car park from 6:45 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Archie had to pay for 1 hour and 54 minutes
= 2.80 + 2.50 + 2.50
= $7.80
(b)
1 h = 60 min
From 6:45 p.m. to 7:45 p.m.:
1 h
Amount that Cathy had to pay from 6:45 p.m. to 7:45 p.m = $2.80
From 7:45 p.m. to 10:00 p.m.: 2 h 15 min
2 h 15 min = 2 x 60 + 15 = 135 min
Number of sets of additional 30 minutes in 2 h 15 min
= 135 ÷ 30
= 4 r 15
Number of sets of additional 30 minutes that Cathy had to pay for
= 4 + 1
= 5
Amount that Cathy had to pay for all the additional 30 minutes or part thereof for 2 h 15 min
= 5 x 2.50
= $12.50
From 10:00 p.m. to 6.30. a.m.
Amount that Cathy had to pay from 10:00 to 6.30 a.m. = $12
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 Cathy had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 2.50
= $22.50
Total amount that Cathy had to pay
= 2.80 + 12.50 + 12 + 22.50
= $49.80
Answer(s): (a) $7.80; (b) $49.80
