- Oscar parked his car at the carpark at 11.00 a.m. for 1 hour and 50 minutes. How much did he have to pay?
- Yoko parked her car at the car park from 2:50 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Oscar had to pay for 1 hour and 50 minutes
= 1.70 + 0.80 + 0.80
= $3.30
(b)
1 h = 60 min
From 2:50 p.m. to 3:50 p.m.:
1 h
Amount that Yoko had to pay from 2:50 p.m. to 3:50 p.m = $1.70
From 3:50 p.m. to 10:00 p.m.: 6 h 10 min
6 h 10 min = 6 x 60 + 10 = 370 min
Number of sets of additional 30 minutes in 6 h 10 min
= 370 ÷ 30
= 12 r 10
Number of sets of additional 30 minutes that Yoko had to pay for
= 12 + 1
= 13
Amount that Yoko had to pay for all the additional 30 minutes or part thereof for 6 h 10 min
= 13 x 0.80
= $10.40
From 10:00 p.m. to 6.30. a.m.
Amount that Yoko had to pay from 10:00 to 6.30 a.m. = $5
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Yoko had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 0.80
= $7.20
Total amount that Yoko had to pay
= 1.70 + 10.40 + 5 + 7.20
= $24.30
Answer(s): (a) $3.30; (b) $24.30
