Rachel paid $55.50 for renting a kayak starting from 14 00. What would be the latest time she must return the kayak to the shop?
Amount that Rachel paid for all the additional
12 hours
= 55.50 - 11.50
= $44
Number of sets of additional
12 hours
= 44 ÷ 5.50
= 8
Total additional time that Rachel paid for
= 8 x
12= 4 h
Total time that Rachel paid for
= 1 + 4
= 5 h
5 h after 14 00 = 19 00
Latest time that Rachel must return the kayak to the shop: 19 00
Answer(s): 19 00
