Answer:
The total distance the bird travels is d.
Explanation:
Each train travels at the speed s. They will meet at the center, a distance d/2 (which is where the bird might be crushed). Each train travels the same distance d/2 in a time t which is also equal for both. This is also the time the bird spends travelling between them.
For any of the train, the time t is the distance divided by the speed.
The bird travels at the speed of 2s. Its distance is given by the product of its speed and the time taken.

150x2=300 90x2=180
the plane is travelling at 180mph
Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
