Question

what is the average velocity of a train which covers 400 km in 5 hours??

Answer 1

Answer:

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:

80 km/hr

Explanation:

Given,

Displacement of the train = 400 km

Time taken to cover = 5 hours

Therefore,

Average velocity of the train

$= \frac{total \: displacement}{total \: time \: taken}$

$= \frac{400 \: km}{5 \: hr}$

= 80 km/hr (Ans)
