Q) [Prob: in attachment. ]From the above figure, find the cruising speed of plane?
options-a)450 b)550 c)650 d)none
I have done this in following way:
B to A -> 7 hrs and A to B -> 4 hrs
So, time ratio = 7/4
As distance is constant, speed ratio = (4/7) = (u-50)/(u+50)
Solving i am getting u = 550/3
In material, solution is given as:-
Avg speed = (6000/11) = 2(u-50)(u+50)/(2u) => u = 550
I could understand the given solution, but i am not able to get why my method is giving different solution.
In triangle ABC angle A is 60 degree
