- Fabian parked his car at the carpark at 4.00 p.m. for 1 hour and 28 minutes. How much did he have to pay?
- Anna parked her car at the car park from 1:35 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Fabian had to pay for 1 hour and 28 minutes
= 2.70 + 2.10
= $4.80
(b)
1 h = 60 min
From 1:35 p.m. to 2:35 p.m.:
1 h
Amount that Anna had to pay from 1:35 p.m. to 2:35 p.m = $2.70
From 2:35 p.m. to 10:00 p.m.: 7 h 25 min
7 h 25 min = 7 x 60 + 25 = 445 min
Number of sets of additional 30 minutes in 7 h 25 min
= 445 ÷ 30
= 14 r 25
Number of sets of additional 30 minutes that Anna had to pay for
= 14 + 1
= 15
Amount that Anna had to pay for all the additional 30 minutes or part thereof for 7 h 25 min
= 15 x 2.10
= $31.50
From 10:00 p.m. to 6.30. a.m.
Amount that Anna had to pay from 10:00 to 6.30 a.m. = $7
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 Anna had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.10
= $6.30
Total amount that Anna had to pay
= 2.70 + 31.50 + 7 + 6.30
= $47.50
Answer(s): (a) $4.80; (b) $47.50
