- Luis parked his car at the carpark at 9.00 a.m. for 1 hour and 25 minutes. How much did he have to pay?
- Julie parked her car at the car park from 1:10 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Luis had to pay for 1 hour and 25 minutes
= 2.70 + 1.90
= $4.60
(b)
1 h = 60 min
From 1:10 p.m. to 2:10 p.m.:
1 h
Amount that Julie had to pay from 1:10 p.m. to 2:10 p.m = $2.70
From 2:10 p.m. to 10:00 p.m.: 7 h 50 min
7 h 50 min = 7 x 60 + 50 = 470 min
Number of sets of additional 30 minutes in 7 h 50 min
= 470 ÷ 30
= 15 r 20
Number of sets of additional 30 minutes that Julie had to pay for
= 15 + 1
= 16
Amount that Julie had to pay for all the additional 30 minutes or part thereof for 7 h 50 min
= 16 x 1.90
= $30.40
From 10:00 p.m. to 6.30. a.m.
Amount that Julie had to pay from 10:00 to 6.30 a.m. = $10
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 Julie had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.90
= $17.10
Total amount that Julie had to pay
= 2.70 + 30.40 + 10 + 17.10
= $60.20
Answer(s): (a) $4.60; (b) $60.20
