Two crews working toward each other are 9.45 miles apart. one crew paves 1.5 miles per day, and the other paves 1.2 mi per day. how long will it take them to meet?
show work my trouble is not in the solving of the problem its the figuring out how to set up the equation.

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. round your answer to the nearest tenth.
