Find average speed aptitude question - Kinematics - Physics problem solver

A bus covers 60 kilometer distance between 2 p.m. and 4 p.m (2 hours time). How fast (speed) was it going ?


distance = 60
time = 2
v =  d / t
speed = 60 / 2
speed = 30
So the speed is 30
Here, first we have to calculate how many hours the bus has traveled. This is time. Divide the total distance by this time to get the average speed of the device.

Kinematics :

The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it.

Kinematics Formulas :

v =  d / t

d =  v * t

t =  d / v


where,

d = distance
t = time
v = speed
a = acceleration
