Linda paid $15 for renting a surfboard starting from 16 00. What would be the latest time she must return the surfboard to the shop?
Amount that Linda paid for all the additional
12 hours
= 15 - 4.50
= $10.50
Number of sets of additional
12 hours
= 10.50 ÷ 1.50
= 7
Total additional time that Linda paid for
= 7 x
12= 3
12 h
Total time that Linda paid for
= 1 + 3
12= 4
12 h
4
12 h after 16 00 = 20 30
Latest time that Linda must return the surfboard to the shop: 20 30
Answer(s): 20 30
