- Vaidev parked his car at the carpark at 11.00 a.m. for 1 hour and 23 minutes. How much did he have to pay?
- Joelle parked her car at the car park from 7:50 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Vaidev had to pay for 1 hour and 23 minutes
= 1.50 + 1.10
= $2.60
(b)
1 h = 60 min
From 7:50 p.m. to 8:50 p.m.:
1 h
Amount that Joelle had to pay from 7:50 p.m. to 8:50 p.m = $1.50
From 8:50 p.m. to 10:00 p.m.: 1 h 10 min
1 h 10 min = 1 x 60 + 10 = 70 min
Number of sets of additional 30 minutes in 1 h 10 min
= 70 ÷ 30
= 2 r 10
Number of sets of additional 30 minutes that Joelle had to pay for
= 2 + 1
= 3
Amount that Joelle had to pay for all the additional 30 minutes or part thereof for 1 h 10 min
= 3 x 1.10
= $3.30
From 10:00 p.m. to 6.30. a.m.
Amount that Joelle had to pay from 10:00 to 6.30 a.m. = $9
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 Joelle had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.10
= $7.70
Total amount that Joelle had to pay
= 1.50 + 3.30 + 9 + 7.70
= $21.50
Answer(s): (a) $2.60; (b) $21.50
