A traveler walks a certain distance. Had he gone half a
kilometer an hour faster , he would have walked it in 4/5
of the time, and had he gone half a Kilometer an hour
slower, he would have walked 2 ½ hr longer. What is the
distance?
Answer Posted / naveen yadav
let d be distance and x be speed and t be time.
hence ,
d / (x+1/2) = 4/5 * t
and d / (x-1/2) = 5/2 + t
solving we get d = 15.
