- Fred parked his car at the carpark at 10.00 a.m. for 1 hour and 46 minutes. How much did he have to pay?
- Emma parked her car at the car park from 5:15 p.m. on Monday to 10 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 46 minutes
= 2.10 + 1.60 + 1.60
= $5.30
(b)
1 h = 60 min
From 5:15 p.m. to 6:15 p.m.:
1 h
Amount that Emma had to pay from 5:15 p.m. to 6:15 p.m = $2.10
From 6:15 p.m. to 10:00 p.m.: 3 h 45 min
3 h 45 min = 3 x 60 + 45 = 225 min
Number of sets of additional 30 minutes in 3 h 45 min
= 225 ÷ 30
= 7 r 15
Number of sets of additional 30 minutes that Emma had to pay for
= 7 + 1
= 8
Amount that Emma had to pay for all the additional 30 minutes or part thereof for 3 h 45 min
= 8 x 1.60
= $12.80
From 10:00 p.m. to 6.30. a.m.
Amount that Emma had to pay from 10:00 to 6.30 a.m. = $12
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 Emma had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.60
= $11.20
Total amount that Emma had to pay
= 2.10 + 12.80 + 12 + 11.20
= $38.10
Answer(s): (a) $5.30; (b) $38.10
