- Bobby parked his car at the carpark at 1.00 p.m. for 1 hour and 36 minutes. How much did he have to pay?
- Usha parked her car at the car park from 2:35 p.m. on Monday to 11 a.m. on Tuesday. Find the amount of parking fee that she had to pay.
(a)
Amount that Bobby had to pay for 1 hour and 36 minutes
= 1.60 + 1.10 + 1.10
= $3.80
(b)
1 h = 60 min
From 2:35 p.m. to 3:35 p.m.:
1 h
Amount that Usha had to pay from 2:35 p.m. to 3:35 p.m = $1.60
From 3:35 p.m. to 10:00 p.m.: 6 h 25 min
6 h 25 min = 6 x 60 + 25 = 385 min
Number of sets of additional 30 minutes in 6 h 25 min
= 385 ÷ 30
= 12 r 25
Number of sets of additional 30 minutes that Usha had to pay for
= 12 + 1
= 13
Amount that Usha had to pay for all the additional 30 minutes or part thereof for 6 h 25 min
= 13 x 1.10
= $14.30
From 10:00 p.m. to 6.30. a.m.
Amount that Usha had to pay from 10:00 to 6.30 a.m. = $8
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 Usha had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.10
= $9.90
Total amount that Usha had to pay
= 1.60 + 14.30 + 8 + 9.90
= $33.80
Answer(s): (a) $3.80; (b) $33.80
