Answer 1

Given :

• A bus covers 128 km. in 2 hours.
• A Train covers 240 km. in 3 hours.

To Find :

• Ratio of their Speed.

Solution :

For Bus :

$\longmapsto\tt{Distance\:Covered=128km}$

$\longmapsto\tt{Time\:Taken=2\:hours}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{\cancel\dfrac{128}{2}}$

$\longmapsto\tt\bold{64km/hr}$

For Train :

$\longmapsto\tt{Distance\:Covered=240km}$

$\longmapsto\tt{Time\:Taken=3\:hours}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{\cancel\dfrac{240}{3}}$

$\longmapsto\tt\bold{80km/hr}$

Now ,

$\longmapsto\tt{\cancel\dfrac{64}{80}}$

$\longmapsto\tt{\dfrac{4}{5}}$

$\longmapsto\tt\bold{4:5}$

So , The Ratio of their speeds is 4:5..

_______________________

Speed :

• It is defined as the distance travelled by an object per unit time.
• Speed = Distance/Time.
• Speed is a scalur quantity.
• Speed of an object is always positive.
