To convert speed from miles per second to miles per hour, we need to multiply by 3600 (60 seconds x 60 minutes). Therefore,

11eaa3e3_41ab_24dc_a4ea_457faba007d2_TB4068_11 miles/second x 3600 seconds/hour = 39,600,000 miles/hour

11eaa3e3_41ab_24dd_a4ea_b5b4248bae06_TB4068_11 miles/second x 3600 seconds/hour = 39,600,020 miles/hour

Since the speed of light is generally considered to be a constant value, we can take the average of these two values to get:

(39,600,000 miles/hour + 39,600,020 miles/hour) / 2 = 39,600,010 miles/hour

We can simplify this to 670 million miles/hour (rounded to the nearest million). Therefore, the best choice is A: 670 million miles/hr.
