Question

A bus travels 54 km in 90 min. Calculate the speed of the bus in m/s.

Answer 1

Answer:

Speed = distance / time = 54 km / (3/2) hr = 54*2 / 3 = 18*2 = 36kmph . A bus travels 54 km in 90 minutes. the speed of the bus is 36 kmph.

Answer 2

$\large{ \underline{ \underline{ \sf{ \purple{Given :}}}}}$

• A bus travels 54 km in 90 minutes .

$\large{ \underline{ \underline{ \sf{ \pink{To \: Find :}}}}}$

• Speed of bus in m/s .

$\large{ \underline{ \underline{ \sf{ \red{Solution :}}}}}$

• $\\ \implies\bf{Time\:Taken\:(t)=90\:min=5400\:sec}$

$\huge{ \underline{ \underline{ \sf{ \green{Using \: Formula :}}}}}$

$\implies\bf{Speed= \sf\orange{\dfrac{Distance}{Time}}}$

$\large{ \underline{ \underline{ \sf{ \blue{Putting \: Values :}}}}}$

$\implies\bf{\dfrac{540{\cancel{00}}}{54{\cancel{00}}}}$

$\implies\bf{\cancel\dfrac{540}{54}}$

$\implies\bf{10\:m/s}$

$\small{ \underline{ \boxed{ \sf{ \pink{So , The \: Speed \: of \: the \: bus \: is \: 10 m/s .</p><p>}}}}}$

Speed : -

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

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