Question

Choose the correct measure of an astronomical unit. 9.3 million miles .93 million miles 93 million miles 930 million miles

Answer 1

By definition, an astronomical unit in miles is given by:
 $1 AU = 9.3 * 10 ^ 7 miles$
 As it is in exponential notation, then we must rewrite.
 $9.3 * 10 ^ 7 = 93,000,000 miles$
 Therefore, an astronomical unit is:
 93 million miles
 Answer:
 93 million miles
