3.5t + 4t = 4 - I did this since the walked the same amount of time and the total distanace covered was 4 miles

Answer:

It will take 0.53 hours to meet.

Step-by-step explanation:

Amanda and Alexis live 4 miles apart.

Distance between them = 4 miles.

Amanda walks at a rate of 3.5 miles per hour and Alexis walks at a rate of 4 miles per hour.

Speed of Amanda = 3.5 mph

Speed of Alexis = 4 mph

Let the time of meeting be t.

We have total distance traveled when they meet = 4

     3.5 t + 4 t = 4

      7.5t = 4

           t = 0.53 hours

It will take 0.53 hours to meet.
