- Xavier parked his car at the carpark at 3.00 p.m. for 1 hour and 7 minutes. How much did he have to pay?
- Xylia parked her car at the car park from 1:40 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Xavier had to pay for 1 hour and 7 minutes
= 2.80 + 1.90
= $4.70
(b)
1 h = 60 min
From 1:40 p.m. to 2:40 p.m.:
1 h
Amount that Xylia had to pay from 1:40 p.m. to 2:40 p.m = $2.80
From 2:40 p.m. to 10:00 p.m.: 7 h 20 min
7 h 20 min = 7 x 60 + 20 = 440 min
Number of sets of additional 30 minutes in 7 h 20 min
= 440 ÷ 30
= 14 r 20
Number of sets of additional 30 minutes that Xylia had to pay for
= 14 + 1
= 15
Amount that Xylia had to pay for all the additional 30 minutes or part thereof for 7 h 20 min
= 15 x 1.90
= $28.50
From 10:00 p.m. to 6.30. a.m.
Amount that Xylia had to pay from 10:00 to 6.30 a.m. = $8
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 Xylia had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.90
= $13.30
Total amount that Xylia had to pay
= 2.80 + 28.50 + 8 + 13.30
= $52.60
Answer(s): (a) $4.70; (b) $52.60
