Question

a man runs 1200 m on a straight line in 4 minutes.find the velocity?​

Answer 1

Answer:

5m/s

Explanation:

velocity=displacement/time

1200/4×60 =5m/s

Answer 2

Concept:

We need to apply the equation of velocity given as the ratio of distance with respect to time. Mathematical expression of velocity becomes- Velocity = distance / time

Given:

Distance ran by man in a straight line = 1200 m

Time taken by a man to run 1200 m is 4 minutes

Find:

We need to determine the velocity of the man running in a straight line.

Solution:

When something is moving, its velocity is how quickly its direction is changing as seen from a particular angle and as measured by a particular unit of time.

In order to be defined, the physical vector quantity known as velocity needs to have both a magnitude and a direction.

We know, Velocity is expressed by the formula- velocity = distance/ time

We have, distance as 1200 m and time as 4 minutes. We first need to convert the time given in minutes to seconds

4 min × 60 second = 240 seconds.

Thus, time, t = 240 seconds and d = 1200 m

Therefore, the equation for velocity- v = d/t becomes

v  = 1200 / 240

v = 5 m/s

Thus, the velocity of a man is 5m/s.
