ye dummy ques lagra h kyonki jab 1st case me A ne hara dia B ko lead dene ke baad bhi to 2nd case me B kaise hara sakta h A ko lead dene ke baad :/
A to keher thadega agli baar me..ya ulta sochen to B jada tagda h A se..so speed constant ni h..pehle case me speed(A)>speed(B) and in 2nd case speed(B)>speed(A)
and jab constant speed hi ni h..to sirif distance se speed kaise nikal lein..

3599sec.........
equation
1000/a-950/b=14..........1
1000/b-978/a=22.............2
where a, b are speed of A &B

total dist=1000m, A takes 14 sec to run 50m, thrfor for 1000m A will take 14*1000/50= 280 secs.

nupur minocha  (9 years ago)

for B
50m- 14 sec.
1m-14/50
1000m-(14/50)*1000
=280 sec
taken by B not A
for A it takes 14 sec less than B
so, (280-14)= 266 sec taken by A
n ques statement aafter full stop is incorrect.
it is only the sol. of frst part

a/b=(1000/950-14b)=(978-22a)/1000
solving b=1
