- Zane parked his car at the carpark at 3.00 p.m. for 1 hour and 17 minutes. How much did he have to pay?
- Kylie parked her car at the car park from 5:35 p.m. on Monday to 8 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Zane had to pay for 1 hour and 17 minutes
= 1.60 + 0.70
= $2.30
(b)
1 h = 60 min
From 5:35 p.m. to 6:35 p.m.:
1 h
Amount that Kylie had to pay from 5:35 p.m. to 6:35 p.m = $1.60
From 6:35 p.m. to 10:00 p.m.: 3 h 25 min
3 h 25 min = 3 x 60 + 25 = 205 min
Number of sets of additional 30 minutes in 3 h 25 min
= 205 ÷ 30
= 6 r 25
Number of sets of additional 30 minutes that Kylie had to pay for
= 6 + 1
= 7
Amount that Kylie had to pay for all the additional 30 minutes or part thereof for 3 h 25 min
= 7 x 0.70
= $4.90
From 10:00 p.m. to 6.30. a.m.
Amount that Kylie had to pay from 10:00 to 6.30 a.m. = $12
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 Kylie had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 0.70
= $2.10
Total amount that Kylie had to pay
= 1.60 + 4.90 + 12 + 2.10
= $20.60
Answer(s): (a) $2.30; (b) $20.60
