Question

A bus travels 54 km is 90 minutes. Calculate the speed of the bus

Answer 1

Answer:

90min = 1.5 hr

speed = 54/ 1.5

= 540/ 15

= 36 Km/ hr.

Answer 2

Given :

A bus travels 54 km in 90 minutes .

To Find :

Speed of bus in m/s .

Solution :

$\longmapsto\tt{Distance\:(s)=54\:km=54,000\:m}$

$\longmapsto\tt{Time\:Taken\:(t)=90\:min=5400\:sec}$

Using Formula :

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

Putting Values :

$\longmapsto\tt{\dfrac{540{\cancel{00}}}{54{\cancel{00}}}}$

$\longmapsto\tt{\cancel\dfrac{540}{54}}$

$\longmapsto\tt\bf{10\:m/s}$

So , The Speed of the bus is 10 m/s .

____________________

Speed : -

It is distance travelled by an object per unit time. It is a scalur quantity . Speed of an object is always positive.

Speed=$\dfrac{Distance}{Time\:Taken}$
