Two planes leave Los Angeles at the same time one heading south to San Diego while the other heads North to San Francisco to San Diego plane flies 50 March 3rd on the San Francisco plane in 1/2 hour the planes are 275 miles apart what are their speeds

San Diego plane traveling at 250

San Fran plane traveling at 300

Step-by-step explanation:

(1/2)(x-50) + (1/2)x = 275

(x-50) + x = 550

x - 50 = 250 mph (speed of the soutn-bound plane)
