The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter.

You forgot to attach the diagram.as you can see in the picture, the height is 22,000 feet. since the probelm is asking us the distance in nautical miles, we are going to convert 22,000 ft to nautical miles first: nautical miles.now, the only thing we need to do to find the maximum  distance that a radio transmitter signal can be sent is replace  that height in our expression: nautical miles  we can conclude that  maximum distance that a radio transmitter signal can be sent is 2.3 nautical miles.
