Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:
plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.
The time spent (t₁) in going east is given by:
The time spent (t₂) in going east is given by:
The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours
Therefore the one way distance is 1400 miles
