Barbara paid $8 for renting a paddle boat starting from 12 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Barbara paid for all the additional
12 hours
= 8 - 3.50
= $4.50
Number of sets of additional
12 hours
= 4.50 ÷ 1.50
= 3
Total additional time that Barbara paid for
= 3 x
12= 1
12 h
Total time that Barbara paid for
= 1 + 1
12= 2

12 h after 12 00 = 14 30
Latest time that Barbara must return the paddle boat to the shop: 14 30
