Penelope 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 Penelope paid for all the additional
12 hours
= 11.50 - 6.50
= $5
Number of sets of additional
12 hours
= 5 ÷ 2.50
= 2
Total additional time that Penelope paid for
= 2 x
12= 1 h
Total time that Penelope paid for
= 1 + 1
= 2 h
2 h after 15 00 = 17 00
Latest time that Penelope must return the surfboard to the shop: 17 00
Answer(s): 17 00
