Cathy paid $28 for renting a kayak starting from 14 00. What would be the latest time she must return the kayak to the shop?
Amount that Cathy paid for all the additional
12 hours
= 28 - 11.50
= $16.50
Number of sets of additional
12 hours
= 16.50 ÷ 5.50
= 3
Total additional time that Cathy paid for
= 3 x
12= 1
12 h
Total time that Cathy paid for
= 1 + 1
12= 2
