- Cody parked his car at the carpark at 7.00 p.m. for 1 hour and 8 minutes. How much did he have to pay?
- Nora parked her car at the car park from 7:45 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Cody had to pay for 1 hour and 8 minutes
= 2.40 + 1.70
= $4.10
(b)
1 h = 60 min
From 7:45 p.m. to 8:45 p.m.:
1 h
Amount that Nora had to pay from 7:45 p.m. to 8:45 p.m = $2.40
From 8:45 p.m. to 10:00 p.m.: 1 h 15 min
1 h 15 min = 1 x 60 + 15 = 75 min
Number of sets of additional 30 minutes in 1 h 15 min
= 75 ÷ 30
= 2 r 15
Number of sets of additional 30 minutes that Nora had to pay for
= 2 + 1
= 3
Amount that Nora had to pay for all the additional 30 minutes or part thereof for 1 h 15 min
= 3 x 1.70
= $5.10
From 10:00 p.m. to 6.30. a.m.
Amount that Nora had to pay from 10:00 to 6.30 a.m. = $6
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 Nora had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.70
= $15.30
Total amount that Nora had to pay
= 2.40 + 5.10 + 6 + 15.30
= $28.80
Answer(s): (a) $4.10; (b) $28.80
