- Ben parked his car at the carpark at 5.00 p.m. for 1 hour and 47 minutes. How much did he have to pay?
- Kylie parked her car at the car park from 1:20 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ben had to pay for 1 hour and 47 minutes
= 2.90 + 2.30 + 2.30
= $7.50
(b)
1 h = 60 min
From 1:20 p.m. to 2:20 p.m.:
1 h
Amount that Kylie had to pay from 1:20 p.m. to 2:20 p.m = $2.90
From 2:20 p.m. to 10:00 p.m.: 7 h 40 min
7 h 40 min = 7 x 60 + 40 = 460 min
Number of sets of additional 30 minutes in 7 h 40 min
= 460 ÷ 30
= 15 r 10
Number of sets of additional 30 minutes that Kylie had to pay for
= 15 + 1
= 16
Amount that Kylie had to pay for all the additional 30 minutes or part thereof for 7 h 40 min
= 16 x 2.30
= $36.80
From 10:00 p.m. to 6.30. a.m.
Amount that Kylie had to pay from 10:00 to 6.30 a.m. = $6
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 Kylie had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.30
= $6.90
Total amount that Kylie had to pay
= 2.90 + 36.80 + 6 + 6.90
= $52.60
Answer(s): (a) $7.50; (b) $52.60
