REQUIRED:

find speed in :

1): cm/sec

2): m/sec

3): km/hour

Explanation:

As we know :

$speed = distance \time$

putting values:

3000m /300sec

so

speed is equal 10m/sec ANSWER

Now convert meter (m) into cm:

[1m = 100cm

SO:

speed = 10 multiply 100 = 1000cm/sec ANSWER

in km/ h are given already in given data.
