Question

Two trains A and B start moving at the same time. The data regarding the motion of these trains is given in the following table. Identify which train has uniform motion and which one has non- uniform motion. Determine speed of train A in SI unit.

Answer 1

According to question:-

(i) From the graph, we can conclude that train A has uniform motion as it covers equal distance in equal intervals of time.

(ii) Speed,

$= \frac{distance \: (in \: 1 \: hr)}{time \: (in \: 1 \: hr)}$

$= \frac{60 \: km}{1 \: hour}$

$= 60 \: km \: per \: hour$
