- Sean parked his car at the carpark at 10.00 a.m. for 1 hour and 9 minutes. How much did he have to pay?
- Mary parked her car at the car park from 4:45 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Sean had to pay for 1 hour and 9 minutes
= 2.10 + 1.80
= $3.90
(b)
1 h = 60 min
From 4:45 p.m. to 5:45 p.m.:
1 h
Amount that Mary had to pay from 4:45 p.m. to 5:45 p.m = $2.10
From 5:45 p.m. to 10:00 p.m.: 4 h 15 min
4 h 15 min = 4 x 60 + 15 = 255 min
Number of sets of additional 30 minutes in 4 h 15 min
= 255 ÷ 30
= 8 r 15
Number of sets of additional 30 minutes that Mary had to pay for
= 8 + 1
= 9
Amount that Mary had to pay for all the additional 30 minutes or part thereof for 4 h 15 min
= 9 x 1.80
= $16.20
From 10:00 p.m. to 6.30. a.m.
Amount that Mary had to pay from 10:00 to 6.30 a.m. = $9
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 Mary had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.80
= $16.20
Total amount that Mary had to pay
= 2.10 + 16.20 + 9 + 16.20
= $43.50
Answer(s): (a) $3.90; (b) $43.50
