- Ian parked his car at the carpark at 1.00 p.m. for 1 hour and 25 minutes. How much did he have to pay?
- Sabrina parked her car at the car park from 4:40 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ian had to pay for 1 hour and 25 minutes
= 2.10 + 1.50
= $3.60
(b)
1 h = 60 min
From 4:40 p.m. to 5:40 p.m.:
1 h
Amount that Sabrina had to pay from 4:40 p.m. to 5:40 p.m = $2.10
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 Sabrina had to pay for
= 8 + 1
= 9
Amount that Sabrina had to pay for all the additional 30 minutes or part thereof for 4 h 20 min
= 9 x 1.50
= $13.50
From 10:00 p.m. to 6.30. a.m.
Amount that Sabrina had to pay from 10:00 to 6.30 a.m. = $6
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 Sabrina had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.50
= $13.50
Total amount that Sabrina had to pay
= 2.10 + 13.50 + 6 + 13.50
= $35.10
Answer(s): (a) $3.60; (b) $35.10
