Let the time taken to ride one way be x and the time taken to walk one way be y. The time taken to walk one way and ride back is 1 hour and 30 minutes or 90 minutes. Then x + y = 90 By riding both ways he would have saved 40 min. Therefore, 2y = 90-40 = 50 y = 25 Therefore time taken to ride one way is 25 minutes We know, x + y = 90 or x = 90-25 = 65 Therefore time taken to walk one way is 225 minutes. The time taken to walk both ways is 65 ×2 = 130 minutes
