Pierre parked his car at the carpark from 3.36 p.m to 7 p.m. How much did he pay for his parking?
From 3.36 p.m. to 4.36 p.m.: 1 h
From 4.36 p.m. to 7 p.m.: 2 h 24 min
1 h = 60 min
2 h 24 min = 2 x 60 + 24 = 144 min
Number of sets of addtional 30 min in 3 h 24 min
= 144 ÷ 30
= 4 r 24
Number of sets of 30 min that Pierre had to pay for
= 4 + 1
= 5
Amount that Pierre had to pay for 5 sets of additional 30 min
= 5 x 1.10
= $5.50
Total amount that Pierre had to pay for his parking
= 1.80 + 5.50
= $7.30
Answer(s): $7.30
