fred begins walking at three mi/h. john leaves his house at the same time and walks towards freds house at a rate of 2 mi/h. how long will it be befor thhey meet the distance between the two houses is 4 miles?
What is the time it takes for a person to walk 4 miles at 5 miles an hour?
MAke a 4 inch line and for every hr. they are supposed to walk. for john draw a dash 2 inches away from 1 end of the line. mimic this but for 3 inches for fred and find at what time they will meet.
