A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III.
We know that 1 meter is 0.001 km and that 1 minute is 60 seconds.
To transform 15m/s we into km/min we have to multiply 15 by 0.001 and multiply it by 60.

- its the answer
Answer: 12
Step-by-step explanation:
1260-360-360-360=180
Therefore,180
There a absolute value so mark out the negative and 25 / by 16 is 1 so 1 is your answer if you really do the problem on paper
