Question

Calculate the speed of a person who travels 600km in 8 hrs express in m/s

please urgent will surely mark u the brainliast!!!!!!​

Answer 1

20.833333... m/s or 20 & 5/6 m/s

Step-by-step explanation:

You want to convert km to meters, and hours to seconds. You do "dimensional analysis," which is just multiplying fractions so that units cancel.
`(600 km)/(8hr) * (1hr)/(60mins) * (1min)/(60sec) = (600km)/(28,800sec) = (6km)/(288sec)`

so now we have km/sec, but we need m/s, so...

`(6km)/(288sec) * (1000m)/(1km) = (6000m)/(288sec) = (125m)/(6sec) = 20(5)/(6) m/s = 20.83333... m/s`

Answer 2

20.83 m/s

Step-by-step explanation:

The speed of an object can be found by using the formula

`v = (d)/(t) \\`

d is the distance

t is the time taken

From the question

600 km = 600,000 m

8hrs = 28,800 s

We have

`v = (600000)/(28800) = (6000)/(288) = (125)/(6) \\ = 20.83333...`

We have the final answer as

20.83 m/s

Hope this helps you
