- Jeremy parked his car at the carpark at 1.00 p.m. for 1 hour and 16 minutes. How much did he have to pay?
- Emma parked her car at the car park from 2:15 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Jeremy had to pay for 1 hour and 16 minutes
= 2.90 + 2.40
= $5.30
(b)
1 h = 60 min
From 2:15 p.m. to 3:15 p.m.:
1 h
Amount that Emma had to pay from 2:15 p.m. to 3:15 p.m = $2.90
From 3:15 p.m. to 10:00 p.m.: 6 h 45 min
6 h 45 min = 6 x 60 + 45 = 405 min
Number of sets of additional 30 minutes in 6 h 45 min
= 405 ÷ 30
= 13 r 15
Number of sets of additional 30 minutes that Emma had to pay for
= 13 + 1
= 14
Amount that Emma had to pay for all the additional 30 minutes or part thereof for 6 h 45 min
= 14 x 2.40
= $33.60
From 10:00 p.m. to 6.30. a.m.
Amount that Emma had to pay from 10:00 to 6.30 a.m. = $6
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 Emma had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 2.40
= $7.20
Total amount that Emma had to pay
= 2.90 + 33.60 + 6 + 7.20
= $49.70
Answer(s): (a) $5.30; (b) $49.70
