An aeroplane flies from Achester to Beeton taking 7.7 hours however the return flight takes 11.4 hours. This difference is caused by a constant wind which blows at 22.8 m/s from Achester to Beeton. Assuming that the plane travels at a constant airspeed (i.e. velocity relative to the air) how far away is Beeton from Achester?
(v+22.8)7.7=distance
(v-22.8)11.4=distance
solve for v, then distance.
