- Albert parked his car at the carpark at 9.00 a.m. for 1 hour and 36 minutes. How much did he have to pay?
- Xandra parked her car at the car park from 7:45 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Albert had to pay for 1 hour and 36 minutes
= 2.30 + 1.90 + 1.90
= $6.10
(b)
1 h = 60 min
From 7:45 p.m. to 8:45 p.m.:
1 h
Amount that Xandra had to pay from 7:45 p.m. to 8:45 p.m = $2.30
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 Xandra had to pay for
= 2 + 1
= 3
Amount that Xandra had to pay for all the additional 30 minutes or part thereof for 1 h 15 min
= 3 x 1.90
= $5.70
From 10:00 p.m. to 6.30. a.m.
Amount that Xandra had to pay from 10:00 to 6.30 a.m. = $8
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 Xandra had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.90
= $5.70
Total amount that Xandra had to pay
= 2.30 + 5.70 + 8 + 5.70
= $21.70
Answer(s): (a) $6.10; (b) $21.70
