A to B rate -----

⭐Rate = 500 km/hr

⭐Time = x hrs

⭐distance = 500x km


B to A rate -----

⭐Rate = 700 km/hr

⭐Time = y hrs

⭐distance = 700y km

⭐ EQUATION ⭐

- - - - - - - - - - -

distance = distance

500x = 700 y

x = (7/5)y

------------------------------------


⭐ FORMULA ⭐


Average speed = total distance/total time.


= (500x + 700y) / (x+y)

= (500(7y/5)+700y) / (12y/5)

= 1400y / (12y/5)

= 7000 / 12

= 583 1 / 3 km/hr

Hy mate here is your answer


Step-by-step explanation:

¤When aeroplain fly from A toB

RATE=500KM/HR

Let TIME will be =x

DISTANCE WILL BE =500x

~~~~~~~~~~~~~~~~~~~~~~~~~~~

When it come back means from B to A

RATE=700KM/HR

LET TIME WILL BE =x

DISTANCE WILL BE =700y


{DISTANCE FROM A TO B =DISTANCE FROM B TO A}

》500X=700y

》x=700y/500

》X=7y/5

\\\\\\\\\\\\\\\\\\\\\|\\\\\\\\\\\\\\\\\\\

Average speed =distance/time


500x +700y/ x+y

500×7y/5 + 700y /x +y

700y +700y/12y/5


1400y/12y/5


1400y×5/12y

7000y/ 12y

1750/3KM/HR



Hope its helpful for u dear^_^
