Distance traveled by the signal from a local radio station, d = 20 miles

1 mile = 1609.34 m

Distance, d = 32186.9 m

Speed of the radio signal,

Let t is the time taken by the signal from a local radio station  to travel 20 miles. The speed is given by :

So, the time taken by the signal from a local radio station  to travel 20 miles is . Hence, this is the required solution.
