- Ryan parked his car at the carpark at 11.00 a.m. for 1 hour and 43 minutes. How much did he have to pay?
- Opal parked her car at the car park from 3:40 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Ryan had to pay for 1 hour and 43 minutes
= 1.50 + 0.90 + 0.90
= $3.30
(b)
1 h = 60 min
From 3:40 p.m. to 4:40 p.m.:
1 h
Amount that Opal had to pay from 3:40 p.m. to 4:40 p.m = $1.50
From 4:40 p.m. to 10:00 p.m.: 5 h 20 min
5 h 20 min = 5 x 60 + 20 = 320 min
Number of sets of additional 30 minutes in 5 h 20 min
= 320 ÷ 30
= 10 r 20
Number of sets of additional 30 minutes that Opal had to pay for
= 10 + 1
= 11
Amount that Opal had to pay for all the additional 30 minutes or part thereof for 5 h 20 min
= 11 x 0.90
= $9.90
From 10:00 p.m. to 6.30. a.m.
Amount that Opal had to pay from 10:00 to 6.30 a.m. = $11
From 6.30 a.m. to 11 a.m.: 4 h 30 min
4 h 30 min = 4 x 60 + 30 = 270 min
Number of sets of additional 30 minutes in 4 h 30 min
= 270 ÷ 30
= 9
Amount that Opal had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 0.90
= $8.10
Total amount that Opal had to pay
= 1.50 + 9.90 + 11 + 8.10
= $30.50
Answer(s): (a) $3.30; (b) $30.50
