Question

A rocket travels at a speed of 15000 m/SEC .express in km /hr

Answer 1

Answer:

The rocket ‘travels’ at a ‘speed’ of 54000 km/hr.

Given:

A rocket travels at a speed of 15000 m/s

To find:

The speed of the rocket in km/hr

Explanation:

‘1 hour = 60 minutes’

‘1 minute = 60 seconds’

1 hour = 60 * 60 = 3600 seconds

1 second  $=\frac{1}{3600} h r$

‘1 kilometer = 1000 meter’

1 meter $=\frac{1}{1000} km$

To convert m / s to km / hr, multiply it by $\frac{3600}{1000}$

Speed of the rocket $=15000 * \frac{3600}{1000} =54000 \mathrm{km} / \mathrm{hr}$

Answer 2

Answer:

Bro your answer is 54000km/hr
