- Oliver parked his car at the carpark at 8.00 p.m. for 1 hour and 18 minutes. How much did he have to pay?
- Rachel parked her car at the car park from 5:25 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Oliver had to pay for 1 hour and 18 minutes
= 1.80 + 1.30
= $3.10
(b)
1 h = 60 min
From 5:25 p.m. to 6:25 p.m.:
1 h
Amount that Rachel had to pay from 5:25 p.m. to 6:25 p.m = $1.80
From 6:25 p.m. to 10:00 p.m.: 3 h 35 min
3 h 35 min = 3 x 60 + 35 = 215 min
Number of sets of additional 30 minutes in 3 h 35 min
= 215 ÷ 30
= 7 r 5
Number of sets of additional 30 minutes that Rachel had to pay for
= 7 + 1
= 8
Amount that Rachel had to pay for all the additional 30 minutes or part thereof for 3 h 35 min
= 8 x 1.30
= $10.40
From 10:00 p.m. to 6.30. a.m.
Amount that Rachel had to pay from 10:00 to 6.30 a.m. = $10
From 6.30 a.m. to 8 a.m.: 1 h 30 min
1 h 30 min = 1 x 60 + 30 = 90 min
Number of sets of additional 30 minutes in 1 h 30 min
= 90 ÷ 30
= 3
Amount that Rachel had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.30
= $3.90
Total amount that Rachel had to pay
= 1.80 + 10.40 + 10 + 3.90
= $26.10
Answer(s): (a) $3.10; (b) $26.10
