The distance is $D = 45000 \ m$

Explanation:

From the question we are told that

The time taken is $t = 3.0 *10^{-4 } \ s$

Generally the speed of the radar is equal to the speed of light and this has a value

$c = 3.0*10^{8} \ m /s$

Now the distance covered by the to and fro movement of the radar is mathematically evaluated as

d = c * t

=> $d = 3.0*10^{8} * 3.0*10^{-4}$

=> $d = 90000 \ m$

Therefore the distance between the radar antenna and the object is

$D = \frac{d}{2}$

$D = \frac{ 90000}{2}$

$D = 45000 \ m$
