TRAVEL ?

If you travel at a constant speed and the distance you travel varies directly with your travel timeSuppose in 1.5 hours you can walk 5 miles What is the costant of variation and how did you find this?


You divide the numer of miles travelled by the number of hours and the result - the constant of variation - is 3.66 (recurring) miles per hour.
