- Harry parked his car at the carpark at 5.00 p.m. for 1 hour and 12 minutes. How much did he have to pay?
- Sabrina parked her car at the car park from 3:20 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Harry had to pay for 1 hour and 12 minutes
= 1.60 + 1.20
= $2.80
(b)
1 h = 60 min
From 3:20 p.m. to 4:20 p.m.:
1 h
Amount that Sabrina had to pay from 3:20 p.m. to 4:20 p.m = $1.60
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 Sabrina had to pay for
= 11 + 1
= 12
Amount that Sabrina had to pay for all the additional 30 minutes or part thereof for 5 h 40 min
= 12 x 1.20
= $14.40
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 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 Sabrina had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.20
= $3.60
Total amount that Sabrina had to pay
= 1.60 + 14.40 + 6 + 3.60
= $25.60
Answer(s): (a) $2.80; (b) $25.60
