Natalie paid $29.50 for renting a kayak starting from 17 00. What would be the latest time she must return the kayak to the shop?
Amount that Natalie paid for all the additional
12 hours
= 29.50 - 8.50
= $21
Number of sets of additional
12 hours
= 21 ÷ 3.50
= 6
Total additional time that Natalie paid for
= 6 x
12= 3 h
Total time that Natalie paid for
= 1 + 3
= 4 h
4 h after 17 00 = 21 00
Latest time that Natalie must return the kayak to the shop: 21 00
Answer(s): 21 00
