Answer: a network of several radio telescopes wired together
Explanation:
A radio interferometer combines signals of several radio telescopes which are used in astronomical observations simultaneously to simulate a discretely-sampled single telescope of very large aperture
Interferometer, an instrument that uses the interference patterns formed by waves to measure certain characteristics of the waves themselves or of materials that reflect, refract, or transmit the waves. Interferometers can also be used to make precise measurements of distance.
River shore is located at distance

speed of the woman is given as

now the time taken by the woman to cover the distance is


for the same time interval the dog will run to and fro with speed 4.5 m/s
so the total distance moved by the dog is given by



<em>so the total distance that dog will move is 7200 m or 7.2 km</em>
