Question

A boy starts from home, goes to a shop, which is 5 km away, buys things and comes back in 2 hours. What is the speed with which he travels ?

Answer 1

Answer:

The average speed with which he travels is 5 km/h.

Explanation:

To find : Speed with which he travels.

Given that,

• Shop is 5 km away from home.
• He is coming back to home is 2 hours.

Here,

Total distance after buying things = 5 km + 5 km

= 10 km

Total distance he is covering is 10 km.

Total time he is taking to cover 10 km distance is 2 hours .

We know,

• Speed = Distance/Time

Put distance and time :

$\implies$ Speed = 10/2 km/h

$\implies$ Speed = 5 km/h

Thus,

He is traveling with average speed 5 km/h.

Answer 2

$\large\underline{\underline{\maltese{\purple{\pmb{\mathscr{\:Given :-}}}}}}$

➬ The distance traveled by boy in 1 hr is 5 km

➬ Time = 2 hour

$\large\underline{\underline{\maltese{\orange{\pmb{\mathscr{\:Solution :-}}}}}}$

✴ Formula Used :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{Speed= \frac{Distance}{Time}}}}}}$

➢ Here :

➳ Distance Travelled by boy in 2 hr

➳ 5 km + 5 km

• = 10 km

➳Time = 2 hr

✴ Applying the values :

$\large\qquad{\qquad{\green{:\longmapsto{\underline{\boxed{\sf{ Speed = \frac{10 \: km}{2 \: hr} }}}}}}{\pink{\bigstar}}}$

$\large\qquad{\qquad{\purple{:\longmapsto{\underline{\boxed{\sf{Speed= 5 \: km/hr}}}}}}{\pink{\bigstar}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Therefore

❝ The speed of boy is

• 5 km/ hr .❞
