- Fred parked his car at the carpark at 8.00 a.m. for 1 hour and 4 minutes. How much did he have to pay?
- Tina parked her car at the car park from 3:45 p.m. on Monday to 9 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Fred had to pay for 1 hour and 4 minutes
= 2.60 + 1.70
= $4.30
(b)
1 h = 60 min
From 3:45 p.m. to 4:45 p.m.:
1 h
Amount that Tina had to pay from 3:45 p.m. to 4:45 p.m = $2.60
From 4:45 p.m. to 10:00 p.m.: 5 h 15 min
5 h 15 min = 5 x 60 + 15 = 315 min
Number of sets of additional 30 minutes in 5 h 15 min
= 315 ÷ 30
= 10 r 15
Number of sets of additional 30 minutes that Tina had to pay for
= 10 + 1
= 11
Amount that Tina had to pay for all the additional 30 minutes or part thereof for 5 h 15 min
= 11 x 1.70
= $18.70
From 10:00 p.m. to 6.30. a.m.
Amount that Tina had to pay from 10:00 to 6.30 a.m. = $9
From 6.30 a.m. to 9 a.m.: 2 h 30 min
2 h 30 min = 2 x 60 + 30 = 150 min
Number of sets of additional 30 minutes in 2 h 30 min
= 150 ÷ 30
= 5
Amount that Tina had to pay for all the additional 30 minutes or part thereof for 2 h 30 min
= 5 x 1.70
= $8.50
Total amount that Tina had to pay
= 2.60 + 18.70 + 9 + 8.50
= $38.80
Answer(s): (a) $4.30; (b) $38.80
