Two radio antennas separated byd= 286 m, as shown in Figure P24.7, simultaneously transmit identical signals of the same wavelength. A radio in a car traveling due north receives the signals.

(a) If the car is at the position of the fourth maximum, what is the wavelength of the signals?
(b) How much farther must the car travel to encounter the next minimum in reception? (Hint: Determine the path difference between the two signals at the two locations of the car.)
