Emma paid $16.50 for renting a surfboard starting from 12 00. What would be the latest time she must return the surfboard to the shop?
Amount that Emma paid for all the additional
12 hours
= 16.50 - 6.50
= $10
Number of sets of additional
12 hours
= 10 ÷ 2.50
= 4
Total additional time that Emma paid for
= 4 x
12= 2 h
Total time that Emma paid for
= 1 + 2
= 3 h
3 h after 12 00 = 15 00
Latest time that Emma must return the surfboard to the shop: 15 00
Answer(s): 15 00
