Answer:

They will meet at 3:04 p.m

Step-by-step explanation:

Since they are walking towards each other , that means we should add their speed together:


speed = 1.35 m/s + 1.65 m/s
           = 3 m/s

Now that we have found the speed, we can calculate the time:

time = 720 meters / 3 m/s
       = 240 seconds
       = 4 minutes ( 240 seconds is 4 minutes)
