​

Answer 1

Answer:

the same direction.

hope it helps you friend

Answer 2

Answer:

Relative Speed = 60+40 = 100 kmph

= 100*(5/18) = 250/9 m/sec

Distance = 140+160 = 300 meters

Time = Distance/Speed

\begin{aligned}

300*\frac{9}{250} = \frac{54}{5} \\

= 10.8 \text{ seconds}

\end{aligned}

So the time trains will take to cross each other will be 10.8 seconds
