- Cole parked his car at the carpark at 6.00 p.m. for 1 hour and 50 minutes. How much did he have to pay?
- Sarah parked her car at the car park from 3:50 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Cole had to pay for 1 hour and 50 minutes
= 2.70 + 2.30 + 2.30
= $7.30
(b)
1 h = 60 min
From 3:50 p.m. to 4:50 p.m.:
1 h
Amount that Sarah had to pay from 3:50 p.m. to 4:50 p.m = $2.70
From 4:50 p.m. to 10:00 p.m.: 5 h 10 min
5 h 10 min = 5 x 60 + 10 = 310 min
Number of sets of additional 30 minutes in 5 h 10 min
= 310 ÷ 30
= 10 r 10
Number of sets of additional 30 minutes that Sarah had to pay for
= 10 + 1
= 11
Amount that Sarah had to pay for all the additional 30 minutes or part thereof for 5 h 10 min
= 11 x 2.30
= $25.30
From 10:00 p.m. to 6.30. a.m.
Amount that Sarah had to pay from 10:00 to 6.30 a.m. = $10
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 Sarah had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 2.30
= $16.10
Total amount that Sarah had to pay
= 2.70 + 25.30 + 10 + 16.10
= $54.10
Answer(s): (a) $7.30; (b) $54.10
