HOW MANY HOURS DOES IT TAKE THE HIKER TO WALK n MILES?Answer by gonzo(654)   (Show Source): You can put this solution on YOUR website!Rate times time = distance let R = rate in miles per hour. let T = time in hours. let D = distance in miles. ----- let R = 3 miles per hour. ----- start with D = R * T divide both sides of the equation by R equation becomes: D/R = T which is the same as: T = D / R ----- equation we want to work with is: T = D / R since R = 3, equation becomes: T = D / 3 if we let D = n, equation becomes: T = n / 3 since T = number of hours it takes for hiker to get there, equation becomes: number of hours it takes for hiker to get there = n / 3 ----- answer is: number of hours it takes for hiker to walk n miles is n / 3 hours. ----- example: let n = 300 miles if the hiker is traveling at 3 miles per hour, it will take 300 / 3 = 100 hours to get there -----
