- Archie parked his car at the carpark at 10.00 a.m. for 1 hour and 20 minutes. How much did he have to pay?
- Julie parked her car at the car park from 3:25 p.m. on Monday to 8 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 20 minutes
= 2.70 + 2.40
= $5.10
(b)
1 h = 60 min
From 3:25 p.m. to 4:25 p.m.:
1 h
Amount that Julie had to pay from 3:25 p.m. to 4:25 p.m = $2.70
From 4:25 p.m. to 10:00 p.m.: 5 h 35 min
5 h 35 min = 5 x 60 + 35 = 335 min
Number of sets of additional 30 minutes in 5 h 35 min
= 335 ÷ 30
= 11 r 5
Number of sets of additional 30 minutes that Julie had to pay for
= 11 + 1
= 12
Amount that Julie had to pay for all the additional 30 minutes or part thereof for 5 h 35 min
= 12 x 2.40
= $28.80
From 10:00 p.m. to 6.30. a.m.
Amount that Julie had to pay from 10:00 to 6.30 a.m. = $12
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 Julie had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.40
= $7.20
Total amount that Julie had to pay
= 2.70 + 28.80 + 12 + 7.20
= $50.70
Answer(s): (a) $5.10; (b) $50.70
