_____________________rate_______time_______distance
Off to Durham________290
Return Flight________253________10

RT=D, the uniform rates law for travel

_____________________rate_______time_______distance
Off to Durham________290
Return Flight________253________10_________253*10=2530

Now you know the travel distance, in both direction;
and you can find the "Off to Durham" time for the trip.



_____________________rate_______time___________distance
Off to Durham________290________(t=2530/290)_________2530
Return Flight________253________10_____________253*10=2530

t=2530%2F290=8.72, or 8 hours 44 minutes.
