<PRE><B>Question 319973</B>
208 miles in one direction during a snow storm. 
return trip double the speed and took 4 hours less. 
..
let speed while going be xmph
speed returning will be 2x mph
..
time taken while going = 208/x
time taken on return = 208/2x, 4 hours less
208/x -4 = 208/2x

208/x-208/2x= 4
416-208 /2x=4
208= 8x
x=26 mph speed while going</PRE>
