Question

A car travels 40km in 2 hour.calculate its speed

Answer 1

Answer:

Your answer is 20km/hr

Explanation:

speed= distance÷time

= 40÷ 2

=20

Answer 2

Answer :

➥ The speed of a car = 20 km/hr

Given :

➤ Distance travelled by a car = 40 km

➤ Time taken by a car = 2 hour

To Find :

➤ Speed of a car = ?

Required Solution :

For solving this question, let's first know about speed.

The rate of change of position an any direction.

• Speed is a distance travelled by body.
• Speed has only magnitude.
• Average speed of body is never 0.

Let's Solve this question...

We can find speed of a car by using the formula of Speed which says s = d/t.

Here,

• s is the Speed in km/hr.
• d is the Distance km.
• t is the Time taken in hour.

✎ So let's find speed of a car (s) !

As we know that

$\tt{: \implies Speed = \dfrac{Distance}{Time \: taken}}$

$\tt{: \implies s = \dfrac{d}{t}}$

$\tt{: \implies s = \cancel{\dfrac{40}{2}}}$

$\bf{: \implies \underline{ \: \: \underline{ \red{ \: \: s = 20 \: km/hr\: \: }} \: \: }}$

║Hence, the Speed of a car is 20 km/hr.║
