Answer:
[tex]310.5\frac{miles}{hr}[/tex]
Step-by-step explanation:
Earth's movement around the Sun is constant, so its expressed by: [tex]d=vt[/tex].
However the problem is asking the speed in miles per hour, to do that we need to transform the time from years to hours.
We know that 1 year equals 8760 hours. Then, we replace all values in the equation and isolate [tex]v[/tex]:
[tex]d=vt\\v=\frac{d}{t} \\v=\frac{2.72x10^{6}miles }{8760hours} = 310.5\frac{miles}{hr}[/tex]
Therefore, the speed of the Earth around the Sun is [tex]310.5\frac{miles}{hr}[/tex]
PD: million is equivalent to [tex]10^{6}[/tex]
