Answer:
Given that the 2 trains start at the same time.
Let the 2 trains meet at 'x' miles distance from left hand side.
(i)
The time taken by the first train to reach the distance 'x' will be,
t=x25t=x25
(ii)
The time taken by the second train to reach the distance '195-x' will be,
t=195−x40t=195−x40
As both the times are equal therefore,
Answer:
Answer and Explanation:
Given that the 2 trains start at the same time.
Let the 2 trains meet at 'x' miles distance from left hand side.
(i)
The time taken by the first train to reach the distance 'x' will be,
t
=
x
25
(ii)
The time taken by the second train to reach the distance '195-x' will be,
t
=
195
−
x
40
As both the times are equal therefore,
x
25
=
195
−
x
40
⇒
40
x
=
25
(
195
−
x
)
⇒
40
x
+
25
x
=
25
(
195
)
⇒
65
x
=
25
(
195
)
⇒
x
=
25
(
195
)
65
⇒
x
=
75
miles
Therefore the 2 trains will meet at time,
t
=
75
25
=
3
hours.
