Tina paid $52 for renting a surfboard starting from 12 00. What would be the latest time she must return the surfboard to the shop?
Amount that Tina paid for all the additional
12 hours
= 52 - 13.50
= $38.50
Number of sets of additional
12 hours
= 38.50 ÷ 5.50
= 7
Total additional time that Tina paid for
= 7 x
12= 3
12 h
Total time that Tina paid for
= 1 + 3
12= 4
12 h
4
12 h after 12 00 = 16 30
Latest time that Tina must return the surfboard to the shop: 16 30
Answer(s): 16 30
