- Valen parked his car at the carpark at 1.00 p.m. for 1 hour and 16 minutes. How much did he have to pay?
- Tina parked her car at the car park from 1:40 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Valen had to pay for 1 hour and 16 minutes
= 2.50 + 2.10
= $4.60
(b)
1 h = 60 min
From 1:40 p.m. to 2:40 p.m.:
1 h
Amount that Tina had to pay from 1:40 p.m. to 2:40 p.m = $2.50
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 Tina had to pay for
= 14 + 1
= 15
Amount that Tina had to pay for all the additional 30 minutes or part thereof for 7 h 20 min
= 15 x 2.10
= $31.50
From 10:00 p.m. to 6.30. a.m.
Amount that Tina had to pay from 10:00 to 6.30 a.m. = $7
From 6.30 a.m. to 10 a.m.: 3 h 30 min
3 h 30 min = 3 x 60 + 30 = 210 min
Number of sets of additional 30 minutes in 3 h 30 min
= 210 ÷ 30
= 7
Amount that Tina had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 2.10
= $14.70
Total amount that Tina had to pay
= 2.50 + 31.50 + 7 + 14.70
= $55.70
Answer(s): (a) $4.60; (b) $55.70
