Joelle paid $52 for renting a paddle boat starting from 16 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Joelle paid for all the additional
12 hours
= 52 - 13.50
= $38.50
Number of sets of additional
12 hours
= 38.50 ÷ 5.50
= 7
Total additional time that Joelle paid for
= 7 x
12= 3
12 h
Total time that Joelle paid for
= 1 + 3
12= 4
12 h
4
12 h after 16 00 = 20 30
Latest time that Joelle must return the paddle boat to the shop: 20 30
Answer(s): 20 30
