Diana paid $21.50 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 Diana paid for all the additional
12 hours
= 21.50 - 6.50
= $15
Number of sets of additional
12 hours
= 15 ÷ 2.50
= 6
Total additional time that Diana paid for
= 6 x
12= 3 h
Total time that Diana paid for
= 1 + 3
= 4 h
4 h after 16 00 = 20 00
Latest time that Diana must return the paddle boat to the shop: 20 00
Answer(s): 20 00
