If a body travels 850m in 34 seconds, what is its average velocity in km/h?

To find the average velocity in kilometers per hour (km/h), we need to first convert the distance from meters to kilometers and the time from seconds to hours.

The distance traveled is 850 meters. To convert this to kilometers, we divide by 1,000 (since there are 1,000 meters in a kilometer):

[

850 , \text{m} = \frac{850}{1000} , \text{km} = 0.85 , \text{km}

]

Next, we convert the time from seconds to hours. There are 3,600 seconds in one hour, so we convert 34 seconds as follows:

[

34 , \text{s} = \frac{34}{3600} , \text{hours} \approx 0.009444 , \text{hours}

]

Now we can calculate the average velocity using the formula:

[

\text{Average Velocity} = \frac{\text{Distance}}{\text{Time}}

]

Substituting in the values we calculated:

[

\text{Average Velocity} = \frac{0.85 , \text{km}}{0.009
