Question
Tarun takes 1hr 30 min in walking to a certain place and
riding back. He would have gained 40 min by riding both ways. How long would he take to walk both ways?Solution
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
