Question

. A man walks 7Km in 3 hours and 3Km in 1 hour in the same direction. What is the average speed of the man?

Answer 1

Answer :

• 2.5 km/hr

Given :

• A man walks 7 km in 3 hours.
• Walks 3 km in 1 hour.

To find :

• the average speed of the man

Solution :

⇒ Let's find the Total time and distance.

• Here, we have to find the total time and distance first.

$\sf \longrightarrow Total \: Distance= 7 + 3 \: km$

$\sf \longrightarrow 10 \: km$

$\sf \longrightarrow Total \: Time = 3 + 1 \: hr$

$\sf \longrightarrow 4 \: hr$

⇒ Now, let's find the average speed. (Here, we are finding the speed in km/hr).

$\sf \longrightarrow Average \: Speed = \dfrac{Total \: Distance }{Total \: time }$

$\sf \longrightarrow \dfrac{10}{4} km/hr$

$\sf \longrightarrow 2.5 \: km/hr$

• Therefore, the average speed of man is 2.5 km/hr.
