Howard parked his car at the carpark from 3.38 p.m to 11 p.m. How much did he pay for his parking?
From 3.38 p.m. to 4.38 p.m.: 1 h
From 4.38 p.m. to 11 p.m.: 6 h 22 min
1 h = 60 min
6 h 22 min = 6 x 60 + 22 = 382 min
Number of sets of addtional 30 min in 7 h 22 min
= 382 ÷ 30
= 12 r 22
Number of sets of 30 min that Howard had to pay for
= 12 + 1
= 13
Amount that Howard had to pay for 13 sets of additional 30 min
= 13 x 1.70
= $22.10
Total amount that Howard had to pay for his parking
= 3.00 + 22.10
= $25.10
Answer(s): $25.10
