You can put this solution on YOUR website! Basic relation applied is speed x time = distance. This also means that (time)=(distance)/(speed).
To see how to manage the numbers, set-up a table. Format like: Speed, Time, Distance.
Going: 8 mph, ( ), D
Returning: 6 mph, ( ), D.
You need to fill in the missing time information in the parentheses. That is where you use time=distance/speed. Full table would be:
Going: 8 mph, D/8, D
Returning: 6 mph, D/6, D
The total time from the tabulated information is 
and since total time is also given, 1.75 hours, if you like in decimal form, you then have that:
 , or if you prefer, 
To continue, simply solve for D.
