Vanessa paid $11.50 for renting a surfboard starting from 15 00. What would be the latest time she must return the surfboard to the shop?
Amount that Vanessa paid for all the additional
12 hours
= 11.50 - 5.50
= $6
Number of sets of additional
12 hours
= 6 ÷ 1.50
= 4
Total additional time that Vanessa paid for
= 4 x
12= 2 h
Total time that Vanessa paid for
= 1 + 2
= 3 h
3 h after 15 00 = 18 00
Latest time that Vanessa must return the surfboard to the shop: 18 00
Answer(s): 18 00
