Question

an athele completes a race of 800m in 2 min calculate his speed​

Answer 1

Provided that:

• Distance = 800 metres
• Time = 2 minutes
• Speed = ???

Firstly let us convert min into seconds as the SI unit of time is second!

→ 1 minute = 60 seconds

→ 2 minutes = 2 × 60

→ 2 minutes = 120 seconds

• Henceforth, converted!

~ Now let us use formula to calculate speed and let us solve this question!

→ Speed = Distance/Time

→ Speed = 800/120

→ Speed = 80/12

→ Speed = 40/6

→ Speed = 20/3

→ Speed = 6.66 m/s

→ Speed ≈ 6.7 m/s

• Therefore, speed = 6.7 m/s

Answer 2

➤ Answer

• Speed of the athlete = 6.7 m/s.

➤ Given

• Distance = 800 meters.
• Time taken = 2 minutes.

➤ To Find

• Speed of the athlete.

➤ Step By Step Explanation

Given that

• Distance = 800 meters.
• Time taken = 2 minutes.

We need to find the speed of the athlete.

So let's do it !!

First we need to convert minutes into seconds.

1 minute = 60 seconds

2 minutes = 2 × 60 seconds

120 seconds.

➠ Formula Used

$\dag\underline{\boxed{\purple{Speed=\cfrac{Distance}{Time}}}}$

➠ By substituting the values

Let's substitute the values to find the speed of the athlete.

$\longmapsto\tt Speed = \cancel\cfrac{800}{120} \\ \\\longmapsto\tt{\green{Speed = 6.66\:m/s}}$

➵ Therefore, speed of the athlete = 6.66 m/s ≈ 6.7 m/s.
