- Jenson parked his car at the carpark at 1.00 p.m. for 1 hour and 4 minutes. How much did he have to pay?
- Fanny parked her car at the car park from 2:35 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Jenson had to pay for 1 hour and 4 minutes
= 1.60 + 0.80
= $2.40
(b)
1 h = 60 min
From 2:35 p.m. to 3:35 p.m.:
1 h
Amount that Fanny had to pay from 2:35 p.m. to 3:35 p.m = $1.60
From 3:35 p.m. to 10:00 p.m.: 6 h 25 min
6 h 25 min = 6 x 60 + 25 = 385 min
Number of sets of additional 30 minutes in 6 h 25 min
= 385 ÷ 30
= 12 r 25
Number of sets of additional 30 minutes that Fanny had to pay for
= 12 + 1
= 13
Amount that Fanny had to pay for all the additional 30 minutes or part thereof for 6 h 25 min
= 13 x 0.80
= $10.40
From 10:00 p.m. to 6.30. a.m.
Amount that Fanny had to pay from 10:00 to 6.30 a.m. = $7
From 6.30 a.m. to 10 a.m.: 3 h 30 min
3 h 30 min = 3 x 60 + 30 = 210 min
Number of sets of additional 30 minutes in 3 h 30 min
= 210 ÷ 30
= 7
Amount that Fanny had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 0.80
= $5.60
Total amount that Fanny had to pay
= 1.60 + 10.40 + 7 + 5.60
= $24.60
Answer(s): (a) $2.40; (b) $24.60
