Answer / guest
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.

Answer / shyam
let distance=x , time=t & speed=s &v knw x=s*t .... (1)
1st case x=(s+.5)(4t/5) ..... (2)
2nd case x=(s-.5)(t+ 5/2) ..... (3)
(1) divided by (2) v get speed s = 2
similarly (2) divided by (3) v get time t = 15/2
therefore x = s * t = 2 * 15/2 = 15 km
