Gillian paid $20 for renting a bicycle starting from 17 00. What would be the latest time she must return the bicycle to the shop?
Amount that Gillian paid for all the additional
12 hours
= 20 - 9.50
= $10.50
Number of sets of additional
12 hours
= 10.50 ÷ 3.50
= 3
Total additional time that Gillian paid for
= 3 x
12= 1
12 h
Total time that Gillian paid for
= 1 + 1
12= 2
