- Ryan parked his car at the carpark at 4.00 p.m. for 1 hour and 11 minutes. How much did he have to pay?
- Kimberly parked her car at the car park from 7:15 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ryan had to pay for 1 hour and 11 minutes
= 2.50 + 2.20
= $4.70
(b)
1 h = 60 min
From 7:15 p.m. to 8:15 p.m.:
1 h
Amount that Kimberly had to pay from 7:15 p.m. to 8:15 p.m = $2.50
From 8:15 p.m. to 10:00 p.m.: 1 h 45 min
1 h 45 min = 1 x 60 + 45 = 105 min
Number of sets of additional 30 minutes in 1 h 45 min
= 105 ÷ 30
= 3 r 15
Number of sets of additional 30 minutes that Kimberly had to pay for
= 3 + 1
= 4
Amount that Kimberly had to pay for all the additional 30 minutes or part thereof for 1 h 45 min
= 4 x 2.20
= $8.80
From 10:00 p.m. to 6.30. a.m.
Amount that Kimberly 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 Kimberly had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.20
= $6.60
Total amount that Kimberly had to pay
= 2.50 + 8.80 + 6 + 6.60
= $23.90
Answer(s): (a) $4.70; (b) $23.90
