- Ryan parked his car at the carpark at 7.00 p.m. for 1 hour and 55 minutes. How much did he have to pay?
- Ivory parked her car at the car park from 4:40 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ryan had to pay for 1 hour and 55 minutes
= 1.80 + 1.40 + 1.40
= $4.60
(b)
1 h = 60 min
From 4:40 p.m. to 5:40 p.m.:
1 h
Amount that Ivory had to pay from 4:40 p.m. to 5:40 p.m = $1.80
From 5:40 p.m. to 10:00 p.m.: 4 h 20 min
4 h 20 min = 4 x 60 + 20 = 260 min
Number of sets of additional 30 minutes in 4 h 20 min
= 260 ÷ 30
= 8 r 20
Number of sets of additional 30 minutes that Ivory had to pay for
= 8 + 1
= 9
Amount that Ivory had to pay for all the additional 30 minutes or part thereof for 4 h 20 min
= 9 x 1.40
= $12.60
From 10:00 p.m. to 6.30. a.m.
Amount that Ivory had to pay from 10:00 to 6.30 a.m. = $6
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 Ivory had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.40
= $9.80
Total amount that Ivory had to pay
= 1.80 + 12.60 + 6 + 9.80
= $30.20
Answer(s): (a) $4.60; (b) $30.20
