Answer:-5t + 4t = 3 is the equation can be used to find t, where t is the time it takes for Milla and Luka to meet

Explanation:-

Given: Milla and Luka are 3 kilometers apart and walking toward each other.

⇒ Distance between them = 3 km

Milla's average speed u=5 kilometers per hour

and Luka's v= 4 kilometers per hour.

Therefore the resultant average speed = u+v=(5+4) kilometers per hour.

We know that <em>Distance =speed × time</em>

⇒Distance between them= resultant average speed × time

⇒3=(5+4)×t , where t is time it takes for Milla and Luka to meet

⇒3=5t+4t [distributive property]

Thus , 5t + 4t = 3 is the equation can be used to find t, where t is the time it takes for Milla and Luka to meet
