Ans:15km solution: speed(s)*time(t)=distance(d) walked 1/2km with time 4/5 (s+0.5)((4/5)t)=d --->(1) 1/2km an hour slow, walked 2and half hr long (s-0.5)(t+2.5)=d ----->(2) solving (1) & (2) we get s=...

Answered by: Akshujain on: Oct 25th, 2009

d = 15 kms

x = speed in km/hr
y = time taken

d / x = y  - eq1
d / x + .5 = (4/5)*y - eq 2
d / x - .5 = 2.5 + y - eq 3
solving these three equation we get d = 15 x = 2 y = 7.5
