- Rael parked his car at the carpark at 6.00 p.m. for 1 hour and 4 minutes. How much did he have to pay?
- Anna parked her car at the car park from 2:35 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Rael had to pay for 1 hour and 4 minutes
= 2.30 + 1.90
= $4.20
(b)
1 h = 60 min
From 2:35 p.m. to 3:35 p.m.:
1 h
Amount that Anna had to pay from 2:35 p.m. to 3:35 p.m = $2.30
From 3:35 p.m. to 10:00 p.m.: 6 h 25 min
6 h 25 min = 6 x 60 + 25 = 385 min
Number of sets of additional 30 minutes in 6 h 25 min
= 385 ÷ 30
= 12 r 25
Number of sets of additional 30 minutes that Anna had to pay for
= 12 + 1
= 13
Amount that Anna had to pay for all the additional 30 minutes or part thereof for 6 h 25 min
= 13 x 1.90
= $24.70
From 10:00 p.m. to 6.30. a.m.
Amount that Anna had to pay from 10:00 to 6.30 a.m. = $7
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 Anna had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.90
= $5.70
Total amount that Anna had to pay
= 2.30 + 24.70 + 7 + 5.70
= $39.70
Answer(s): (a) $4.20; (b) $39.70
