tweety Profile Answers by tweety Questions by tweety Apr 5th, 2006 (x/20)-(x/30)=1+1 //1hr late and 1 hr before//then u get distance x =120miles....and the speed at which it walks.....u consider the average speed then u get 24miles/hr......i.e.2xy/(x+y).

Ankit Kamra Apr 7th, 2006 as distance is constantspeed1 * time1=speed2 * time230 * (t-1) = 20 * (t+1)t=5distance == 120
