Milla and luka are 3 kilometers apart and walking toward each other. milla's average speed is 5 kilometers per hour and luka's is 4 kilometers per hour.

which equation can be used to find t, the time it takes for milla and luka to meet?
5t + 4t = 1
5t + 4t = 3
5t – 4t = 0
5t – 4t = 3

Second option is correct.

Step-by-step explanation:

Since we have given that

Speed of Milla = 5 km per hour

Speed of Luka = 4 km per hour

Distance between Milla and Luka = 3 km

Let the time be 't'.

As we know that

So, it becomes,

Distance covered by Milla + Distance covered by Luka = Total distance

Hence, Second option is correct.
