- Neave parked his car at the carpark at 1.00 p.m. for 1 hour and 16 minutes. How much did he have to pay?
- Fanny parked her car at the car park from 6:15 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Neave had to pay for 1 hour and 16 minutes
= 2.10 + 1.60
= $3.70
(b)
1 h = 60 min
From 6:15 p.m. to 7:15 p.m.:
1 h
Amount that Fanny had to pay from 6:15 p.m. to 7:15 p.m = $2.10
From 7:15 p.m. to 10:00 p.m.: 2 h 45 min
2 h 45 min = 2 x 60 + 45 = 165 min
Number of sets of additional 30 minutes in 2 h 45 min
= 165 ÷ 30
= 5 r 15
Number of sets of additional 30 minutes that Fanny had to pay for
= 5 + 1
= 6
Amount that Fanny had to pay for all the additional 30 minutes or part thereof for 2 h 45 min
= 6 x 1.60
= $9.60
From 10:00 p.m. to 6.30. a.m.
Amount that Fanny 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 Fanny had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.60
= $4.80
Total amount that Fanny had to pay
= 2.10 + 9.60 + 8 + 4.80
= $24.50
Answer(s): (a) $3.70; (b) $24.50
