First you get the data:
Time conversion: hours to seconds:
[tex]\bf{2\not{h}*\left(\dfrac{3600 \ seg}{1\not{h}}\right)=7200 \ seg }[/tex]
We calculate the distance, using the formula:
[tex]\bf{d=t*v }[/tex]
[tex]\bf{d=3600\not{seg}*3\frac{m}{\not{m}} }[/tex]
[tex]\bf{d=21600 \ m}[/tex]
Answer: I travel to 21600 meters.
