- Ian parked his car at the carpark at 2.00 p.m. for 1 hour and 54 minutes. How much did he have to pay?
- Zoe parked her car at the car park from 1:40 p.m. on Monday to 8 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 54 minutes
= 2.90 + 2.30 + 2.30
= $7.50
(b)
1 h = 60 min
From 1:40 p.m. to 2:40 p.m.:
1 h
Amount that Zoe had to pay from 1:40 p.m. to 2:40 p.m = $2.90
From 2:40 p.m. to 10:00 p.m.: 7 h 20 min
7 h 20 min = 7 x 60 + 20 = 440 min
Number of sets of additional 30 minutes in 7 h 20 min
= 440 ÷ 30
= 14 r 20
Number of sets of additional 30 minutes that Zoe had to pay for
= 14 + 1
= 15
Amount that Zoe had to pay for all the additional 30 minutes or part thereof for 7 h 20 min
= 15 x 2.30
= $34.50
From 10:00 p.m. to 6.30. a.m.
Amount that Zoe had to pay from 10:00 to 6.30 a.m. = $9
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 Zoe had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.30
= $6.90
Total amount that Zoe had to pay
= 2.90 + 34.50 + 9 + 6.90
= $53.30
Answer(s): (a) $7.50; (b) $53.30
