Question

23. If a car travels 500 m in 5 minutes
its speed in m/s is
(1 Point)
a) 120 m/s
b) 2 m/s
c) 1.6 m/s
d) 20 m/s​

Answer 1

Given :

• Distance covered by a car is 500 m.
• Time Taken by car is 5 minutes.

To Find :

• Speed of Car in m/s.

Solution :

$\longmapsto\tt{Distance=500\:m}$

$\longmapsto\tt{Time\:Taken=5\:min=300\:sec.}$

Using Formula :

$\longmapsto\tt\boxed{Speed=\dfrac{Distance}{Time}}$

Putting Values :

$\longmapsto\tt{\dfrac{5{\cancel{00}}}{3{\cancel{00}}}}$

$\longmapsto\tt{\cancel\dfrac{5}{3}}$

$\longmapsto\tt\bf{1.6\:m/s}$

So , The Speed of the car is 1.6 m/s ..

Option c) 1.6 m/s is Correct ..

_______________________

Speed :

• The distance travelled by an object per unit time is known as Speed .
• Speed is a scalur quantity .
• Average speed of a moving body can't be zero .
• Speed of an object is always positive .

Answer 2

Given :

★ Distance covered by a car is 500 m

★ Time Taken by car is 5 minutes

To Find :

• Speed of Car in m/s.

Solution :

$\implies \sf \: Distance=500\:m$

$\sf \: Time \: Taken=5 \: min=300 \: sec.$

Formula used :

$\implies \sf \: Speed = \frac{distance}{time}$

Putting Values :

$\implies \sf \frac{ \cancel{500}}{ \cancel{300}}$

$\implies\sf \frac{ \cancel{5}}{ \cancel3}$

$\implies \sf \: 1.6m/s$

So , The Speed of the car is 1.6 m/s

$\fbox \red { \sf Option \: (c) \: 1.6 m/s \: is \: Correct}$
