Answer 2

Answer:

It is given that,

Distance travelled by the motor car, d = 500 meters

Time taken by the motorcar, t = 50 seconds

Let v is the speed of the motorcar. It can be calculated as :

$v=\dfrac{d}{t}v= </p><p>t</p><p>d$

$v=\dfrac{500\ m}{50\ s}v= </p><p>50 s</p><p>500 m$

v = 10 m/s

Since, 1 km = 1000 m

and 1 hour = 3600 s

So, v = 36 km/h

So, the speed of the motor car is 36 km/h. Hence, this is the required solution
