- Julian parked his car at the carpark at 12.00 p.m. for 1 hour and 58 minutes. How much did he have to pay?
- Eva parked her car at the car park from 4:50 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Julian had to pay for 1 hour and 58 minutes
= 1.70 + 0.90 + 0.90
= $3.50
(b)
1 h = 60 min
From 4:50 p.m. to 5:50 p.m.:
1 h
Amount that Eva had to pay from 4:50 p.m. to 5:50 p.m = $1.70
From 5:50 p.m. to 10:00 p.m.: 4 h 10 min
4 h 10 min = 4 x 60 + 10 = 250 min
Number of sets of additional 30 minutes in 4 h 10 min
= 250 ÷ 30
= 8 r 10
Number of sets of additional 30 minutes that Eva had to pay for
= 8 + 1
= 9
Amount that Eva had to pay for all the additional 30 minutes or part thereof for 4 h 10 min
= 9 x 0.90
= $8.10
From 10:00 p.m. to 6.30. a.m.
Amount that Eva had to pay from 10:00 to 6.30 a.m. = $7
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 Eva had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 0.90
= $8.10
Total amount that Eva had to pay
= 1.70 + 8.10 + 7 + 8.10
= $24.90
Answer(s): (a) $3.50; (b) $24.90
