an aeroplane flies from A to B rate of 500 km per hour back from B to a at the rate of 700 km per hour the average speed of aeroplane
Answers
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

I hope it helps you
Thankyou
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^_^
