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