Step-by-step explanation:
Lets assume time taken and distance traveled by
A
are
T
and
D
respectively.
So, time taken by
B
=
T
−
3
and distance traveled is
100
−
D
.
V
A
=
3
and
V
B
=
3.5
From above information, we can derive
3
T
=
D
,
and
3.5
(
T
−
3
)
=
100
−
D
.
Solving both, we get
D
=
51
km
Hence, distance from Asansol where they meet
100
−
D
=
49
km.
