1. Asher parked his car at the carpark at 8.00 a.m. for 1 hour and 29 minutes. How much did he have to pay?
2. Victoria 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 Asher had to pay for 1 hour and 29 minutes
= 1.90 + 1.30
= $3.20

(b)
1 h = 60 min

From 3:40 p.m. to 4:40 p.m.: 1 h
Amount that Victoria had to pay from 3:40 p.m. to 4:40 p.m = $1.90

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 Victoria had to pay for 
= 10 + 1
= 11

Amount that Victoria had to pay for all the additional 30 minutes or part thereof for 5 h 20 min
= 11 x 1.30
= $14.30

From 10:00 p.m. to 6.30. a.m. 
Amount that Victoria had to pay from 10:00 to 6.30 a.m. = $7

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 Victoria had to pay for all the additional 30 minutes or part thereof for 4 h 30 min
= 9 x 1.30
= $11.70

Total amount that Victoria had to pay
= 1.90 + 14.30 + 7 + 11.70
= $34.90

Answer(s): (a) $3.20; (b) $34.90
