Fred begins walking toward John house at 3 mi/h. John leaves his house at the same time and walks toward Fred's house on the sam

Tcecarenko [31]

Let us assume as at when they meet, the time elapsed is x hours.

Fred 3 mi/h
John 2 mi/h

Distance = speed * time

Fred = 3x
John = 2x

Houses are 4miles apart.
So: 3x + 2x = 4 5x = 4

x = 4/5 hour = 0.8 hour or 0.8*60 = 48 minutes

Time elapsed is 0.8 hour or 48 minutes.
