Answer 1

Explanation:

For this problem, since the speed is constant, we can use the following equation:

Speed (S) = distance (d)/time (t)

The problem has given us some of the variables we can use to solve the problem as shown below:

S = ?

d = 400 km

t = 8 h

Now to solve the problem, fill in the variables in the original equation like this:

S = d/t

S = 400 km/8 h

S = 50 km/h

Thus, the speed between the two stations is a constant 50 km/h.

Answer 2

Answer:

Distance covered by train S=400 km

Time taken by train to cover this distance ,t=2 hrs

Thus speed of train v= S/t

Thus v=400/2

v=200km/hr

or v=200×1000 m/60×60s

v=200000/3600 m/s

v=55.55m/s
