Step-by-step explanation:
Below is an attachment containing the solution .
3:4,5:2.4 2.4/4*5= 3 (8/4= 2 2*5=10) and 3/2*3= 4,5 (10/2*3=15)
Mathematics is not discovered, it is invented
<span>We just need to solve the system.
k = 528 – 10t
k = 14t
14t=528-10t
24t=528
t=22 minutes
k=14*22=308 kl
Final answer: </span>It will take <span>22</span> minutes for both tanks to hold equal amounts of water. They will each hold 308 kiloliters.
