Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
Average speed is found by dividing total distance by total time..here that is
v = 261 miles/2.5 hours
v = 104.4 miles per hour
If the one-way time was 2.5 hours, then
v = 261 miles/5 hours
v = 52.2 miles per hour (certainly more realistic)
