_____________________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
, or 8 hours 44 minutes.
