Jade paid $22.50 for renting a paddle boat starting from 14 00. What would be the latest time she must return the paddle boat to the shop?
Amount that Jade paid for all the additional
12 hours
= 22.50 - 7.50
= $15
Number of sets of additional
12 hours
= 15 ÷ 2.50
= 6
Total additional time that Jade paid for
= 6 x
12= 3 h
Total time that Jade paid for
= 1 + 3
= 4 h
4 h after 14 00 = 18 00
Latest time that Jade must return the paddle boat to the shop: 18 00
Answer(s): 18 00
