As Return journey is slower, we will go with that
Average Speed = 30 mph
Maximum time allowed = 8 hours

Maximum distance the person should travel = 30 x 8 = 240 miles

Scenario 1:

Person want to leave on Saturday and come back on Sunday
Travel being slower on Sunday @ 30 mph
Maximum time for travel = 8 hours

Therefore, the person should go upto 30 x 8 = 240 miles

Scenario 2:

Person wants to leave on Sunday and come back on Sunday
Return traffic being slower = 30 mph
Maximum time for travel = 8 hours
Max. time for one side = 4 hours

Therefore the person should go upto 30 x 4 = 120 miles
