- Ian parked his car at the carpark at 5.00 p.m. for 1 hour and 13 minutes. How much did he have to pay?
- Gwen parked her car at the car park from 1:15 p.m. on Monday to 10 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ian had to pay for 1 hour and 13 minutes
= 2.20 + 1.70
= $3.90
(b)
1 h = 60 min
From 1:15 p.m. to 2:15 p.m.:
1 h
Amount that Gwen had to pay from 1:15 p.m. to 2:15 p.m = $2.20
From 2:15 p.m. to 10:00 p.m.: 7 h 45 min
7 h 45 min = 7 x 60 + 45 = 465 min
Number of sets of additional 30 minutes in 7 h 45 min
= 465 ÷ 30
= 15 r 15
Number of sets of additional 30 minutes that Gwen had to pay for
= 15 + 1
= 16
Amount that Gwen had to pay for all the additional 30 minutes or part thereof for 7 h 45 min
= 16 x 1.70
= $27.20
From 10:00 p.m. to 6.30. a.m.
Amount that Gwen had to pay from 10:00 to 6.30 a.m. = $6
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 Gwen had to pay for all the additional 30 minutes or part thereof for 3 h 30 min
= 7 x 1.70
= $11.90
Total amount that Gwen had to pay
= 2.20 + 27.20 + 6 + 11.90
= $47.30
Answer(s): (a) $3.90; (b) $47.30
