Gem paid $12.50 for renting a skateboard starting from 16 00. What would be the latest time she must return the skateboard to the shop?
Amount that Gem paid for all the additional
12 hours
= 12.50 - 3.50
= $9
Number of sets of additional
12 hours
= 9 ÷ 1.50
= 6
Total additional time that Gem paid for
= 6 x
12= 3 h
Total time that Gem paid for
= 1 + 3
= 4 h
4 h after 16 00 = 20 00
Latest time that Gem must return the skateboard to the shop: 20 00
Answer(s): 20 00
