Diana paid $12 for renting a surfboard starting from 14 00. What would be the latest time she must return the surfboard to the shop?
Amount that Diana paid for all the additional
12 hours
= 12 - 4.50
= $7.50
Number of sets of additional
12 hours
= 7.50 ÷ 1.50
= 5
Total additional time that Diana paid for
= 5 x
12= 2
12 h
Total time that Diana paid for
= 1 + 2
12= 3
12 h
3
12 h after 14 00 = 17 30
Latest time that Diana must return the surfboard to the shop: 17 30
Answer(s): 17 30
