Answer:
777.9 Mkm
Explanation:
(M = Mega = [tex]10^{6}[/tex])
AU is the Astronomical Unit for distance (1AU=149,597,870.691 km)
The total distance in km then is:
[tex]5.2 * 149,597,870.691 km = 777908927.593 km[/tex]
To give the result in millions, we use the prefix Mega:
[tex](\frac{1M}{10^{6} } ) * 777908927.593 km = 777.9 Mkm[/tex]
