Question

A cover a distance of 200km with a certain speed in 5 hour. What would be the time taken to covered the distance of
180km with the same speed​

Answer 1

$\huge\sf\pink{Answer}$

☞ Your Answer is:4.5 Hours

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ A body covers a distance of 200 km in 5 hours

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ Time taken by the body to cover 180 km?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

Speed of a body is given by,

$\underline{\boxed{\sf Speed = \dfrac{Distance}{Time}}}$

Substituting the given values,

➝ $\sf Speed = \dfrac{Distance}{Time}$

➝ $\sf Speed = \dfrac{200}{5}$

➝ $\sf \red{Speed = 40 \ km/h}$

So now when the body travels 180 km,then,

➳ $\sf Speed = \dfrac{Distance}{Time}$

➳ $\sf 40 = \dfrac{180}{Time}$

➳ $\sf Time = \dfrac{180}{40}$

➳ $\sf \orange{Time = 4.5 \ Hours}$

☆ Speed is a scalar quantity, that is it has only direction

☆ SI unit of speed is m/s

☆ Average Speed = Total Distance/Total Time

Answer 2

→since

→Speed=distance/time

→Therefore,

→Speed of train =240/5

→=48km/h

→ Again

→ Speed×time=distance

Ф Therefore

→ Distance in 10hrs =48×10

→ =480
