Question

It took ramu 6 hours to walk to Raju's house at 2 km/hr. How far is it between Ramu's house and Raja's house ?
please if anyone know then please tell ​

Answer 1

Given :

Time of journey = 6hr

Speed od ramu = 2km/hr

To Find :

Distance between ramu's house and raju's house.

Solution :

❖ Speed is defined as the ratio of distance travelled to the time taken.

• It is a scalar quantity having only magnitude.
• It doesn't has direction.
• It can't be negative or zero.
• SI unit : m/s
• CGS unit : cm/s
• Dimension formula : [L¹T‾¹]

Mathematically, $\underline{\boxed{\bf{\red{v=\dfrac{d}{t}}}}}$

» v denotes speed

» d denotes distance

» t denotes time

By substituting the given values;

➙ v = d / t

➙ 2 = d / 6

➙ d = 2 × 6

➙ d = 12 km

Answer 2

Given :

• It took ramu 6 hours to walk to Raju's house at 2 km/hr

To Find :

• How far is it between Ramu's house and Raja's house ?

Solution :

We have,

• Time of journey(t) = 6 hr
• Speed of ramu(v) = 2 km/hr

We know that,

$\large\underline{\boxed{\blue{\sf d = vt}}}$

Where,

• d = distance
• v = speed
• t = time

Substituting the given values we get,

➙ d = vt

➙ d = 2 × 6

➠ d = 12 km

∴ Distance between ramu's house and raju's house is 12 km.
