- Tommy parked his car at the carpark at 8.00 p.m. for 1 hour and 39 minutes. How much did he have to pay?
- Jade parked her car at the car park from 5:35 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Tommy had to pay for 1 hour and 39 minutes
= 2.40 + 1.60 + 1.60
= $5.60
(b)
1 h = 60 min
From 5:35 p.m. to 6:35 p.m.:
1 h
Amount that Jade had to pay from 5:35 p.m. to 6:35 p.m = $2.40
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 Jade had to pay for
= 6 + 1
= 7
Amount that Jade had to pay for all the additional 30 minutes or part thereof for 3 h 25 min
= 7 x 1.60
= $11.20
From 10:00 p.m. to 6.30. a.m.
Amount that Jade had to pay from 10:00 to 6.30 a.m. = $12
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 Jade had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.60
= $11.20
Total amount that Jade had to pay
= 2.40 + 11.20 + 12 + 11.20
= $36.80
Answer(s): (a) $5.60; (b) $36.80
