1. The problem statement, all variables and given/known data A plane flew 4200 km from Glasgow to Halifax into a head wind. With a tail wind, the plain flew 100km/h faster on the return trip. The total flying time from Glasgow to Halifax and back was 13 h. What was teh flying speed from glasgoq to Halifax? 3. The attempt at a solution Speed x Time = Distance G-H x 4200/x 4200 H-G x+100 4200/(x+100) 4200 TOT 13h 4200/x + 4200/(x+100) = 13 x (x)(x+100) 4200(x+100) + 4200 (x) = (13)(x)(x+100) ..... I kept doing this but none of these type of problems turn out right with me.
