- Pierre parked his car at the carpark at 1.00 p.m. for 1 hour and 40 minutes. How much did he have to pay?
- Kimberly parked her car at the car park from 3:20 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Pierre had to pay for 1 hour and 40 minutes
= 2.10 + 1.60 + 1.60
= $5.30
(b)
1 h = 60 min
From 3:20 p.m. to 4:20 p.m.:
1 h
Amount that Kimberly had to pay from 3:20 p.m. to 4:20 p.m = $2.10
From 4:20 p.m. to 10:00 p.m.: 5 h 40 min
5 h 40 min = 5 x 60 + 40 = 340 min
Number of sets of additional 30 minutes in 5 h 40 min
= 340 ÷ 30
= 11 r 10
Number of sets of additional 30 minutes that Kimberly had to pay for
= 11 + 1
= 12
Amount that Kimberly had to pay for all the additional 30 minutes or part thereof for 5 h 40 min
= 12 x 1.60
= $19.20
From 10:00 p.m. to 6.30. a.m.
Amount that Kimberly had to pay from 10:00 to 6.30 a.m. = $9
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Kimberly had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.60
= $14.40
Total amount that Kimberly had to pay
= 2.10 + 19.20 + 9 + 14.40
= $44.70
Answer(s): (a) $5.30; (b) $44.70
