Bobby parked his car at the carpark from 1.31 p.m to 4 p.m. How much did he pay for his parking?
From 1.31 p.m. to 2.31 p.m.: 1 h
From 2.31 p.m. to 4 p.m.: 1 h 29 min
1 h = 60 min
1 h 29 min = 1 x 60 + 29 = 89 min
Number of sets of addtional 30 min in 2 h 29 min
= 89 ÷ 30
= 2 r 29
Number of sets of 30 min that Bobby had to pay for
= 2 + 1
= 3
Amount that Bobby had to pay for 3 sets of additional 30 min
= 3 x 1.30
= $3.90
Total amount that Bobby had to pay for his parking
= 2.70 + 3.90
= $6.60
Answer(s): $6.60
