Abi paid $28.50 for renting a skateboard starting from 12 00. What would be the latest time she must return the skateboard to the shop?
Amount that Abi paid for all the additional
12 hours
= 28.50 - 10.50
= $18
Number of sets of additional
12 hours
= 18 ÷ 4.50
= 4
Total additional time that Abi paid for
= 4 x
12= 2 h
Total time that Abi paid for
= 1 + 2
= 3 h
3 h after 12 00 = 15 00
Latest time that Abi must return the skateboard to the shop: 15 00
Answer(s): 15 00
