- Japheth parked his car at the carpark at 3.00 p.m. for 1 hour and 28 minutes. How much did he have to pay?
- Elyse parked her car at the car park from 7:25 p.m. on Monday to 9 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Japheth had to pay for 1 hour and 28 minutes
= 2.40 + 1.70
= $4.10
(b)
1 h = 60 min
From 7:25 p.m. to 8:25 p.m.:
1 h
Amount that Elyse had to pay from 7:25 p.m. to 8:25 p.m = $2.40
From 8:25 p.m. to 10:00 p.m.: 1 h 35 min
1 h 35 min = 1 x 60 + 35 = 95 min
Number of sets of additional 30 minutes in 1 h 35 min
= 95 ÷ 30
= 3 r 5
Number of sets of additional 30 minutes that Elyse had to pay for
= 3 + 1
= 4
Amount that Elyse had to pay for all the additional 30 minutes or part thereof for 1 h 35 min
= 4 x 1.70
= $6.80
From 10:00 p.m. to 6.30. a.m.
Amount that Elyse had to pay from 10:00 to 6.30 a.m. = $12
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 Elyse had to pay for all the additional 30 minutes or part thereof for 2 h 30 min
= 5 x 1.70
= $8.50
Total amount that Elyse had to pay
= 2.40 + 6.80 + 12 + 8.50
= $29.70
Answer(s): (a) $4.10; (b) $29.70
