Usha paid $15 for renting a skateboard starting from 15 00. What would be the latest time she must return the skateboard to the shop?
Amount that Usha paid for all the additional
12 hours
= 15 - 7.50
= $7.50
Number of sets of additional
12 hours
= 7.50 ÷ 2.50
= 3
Total additional time that Usha paid for
= 3 x
12= 1
12 h
Total time that Usha paid for
= 1 + 1
12= 2

12 h after 15 00 = 17 30
Latest time that Usha must return the skateboard to the shop: 17 30
