Question

A car covers a distance of 400 metres in 30 seconds what is its speed​

Answer 1

Answer:

Given:

Distance = 400m

Time = 30 sec

To Find:

Speed

Formula:

$\huge\bold\red{\mathfrak{Speed=\frac{distance}{time} }}$

Solution:

Putting the values in given formula:

$\bold{\mathbb{speed=\frac{distance}{time}}}$

$\bold{\mathbb{\implies speed=\frac{400}{30}}}$

$\bold{\mathbb{\implies speed =13.33m/s}}$

Thus ,the speed of the car is ,

$\boxed{\blue{\boxed{\boxed{\mathcal{speed=13.33m/s}}}}}$

Answer 2

Given ,

Distance = 400 m

Time = 30 sec

As we know that ,

☢ The rate of distance is called speed

☢ The SI unit of speed is m/s

☢ It is scalar quantity

Thus ,

$\Rightarrow \sf Speed = \frac{400}{30} \\ \\ \Rightarrow \sf Speed = 13.33 \: \: m/s$

$\therefore \sf \bold{ \underline{The \: speed \: is \: 13.33 \: m/s}}$
