Question

. A train travelling due north on a straight railway
track covers a distance of 5 km in 10 minutes.
What is the speed and the velocity of the train
expressed in SI units?​

Answer 1

Answer:

3km/hr

Explanation:

In 10 min the object covers 5000m

then, in 1 min it covers 'x' m

x= 5000/10 =500m

If the object covers 500m in 1 min then in 1 hour it covers= 500×60 = 3000m =3km

In SI units,

speed = distance/time

= 3km/hr

Since the object is moving in straight line, speed=velocity= 3km/hr
