- Fred parked his car at the carpark at 5.00 p.m. for 1 hour and 51 minutes. How much did he have to pay?
- Xylia 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 Fred had to pay for 1 hour and 51 minutes
= 1.80 + 1.30 + 1.30
= $4.40
(b)
1 h = 60 min
From 5:35 p.m. to 6:35 p.m.:
1 h
Amount that Xylia had to pay from 5:35 p.m. to 6:35 p.m = $1.80
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 Xylia had to pay for
= 6 + 1
= 7
Amount that Xylia had to pay for all the additional 30 minutes or part thereof for 3 h 25 min
= 7 x 1.30
= $9.10
From 10:00 p.m. to 6.30. a.m.
Amount that Xylia had to pay from 10:00 to 6.30 a.m. = $11
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 Xylia had to pay for all the additional 30 minutes or part thereof for 1 h 30 min
= 3 x 1.30
= $3.90
Total amount that Xylia had to pay
= 1.80 + 9.10 + 11 + 3.90
= $25.80
Answer(s): (a) $4.40; (b) $25.80
