- Warren parked his car at the carpark at 4.00 p.m. for 1 hour and 42 minutes. How much did he have to pay?
- Roshel parked her car at the car park from 2:45 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Warren had to pay for 1 hour and 42 minutes
= 2.30 + 1.90 + 1.90
= $6.10
(b)
1 h = 60 min
From 2:45 p.m. to 3:45 p.m.:
1 h
Amount that Roshel had to pay from 2:45 p.m. to 3:45 p.m = $2.30
From 3:45 p.m. to 10:00 p.m.: 6 h 15 min
6 h 15 min = 6 x 60 + 15 = 375 min
Number of sets of additional 30 minutes in 6 h 15 min
= 375 ÷ 30
= 12 r 15
Number of sets of additional 30 minutes that Roshel had to pay for
= 12 + 1
= 13
Amount that Roshel had to pay for all the additional 30 minutes or part thereof for 6 h 15 min
= 13 x 1.90
= $24.70
From 10:00 p.m. to 6.30. a.m.
Amount that Roshel had to pay from 10:00 to 6.30 a.m. = $10
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 Roshel had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.90
= $13.30
Total amount that Roshel had to pay
= 2.30 + 24.70 + 10 + 13.30
= $50.30
Answer(s): (a) $6.10; (b) $50.30
