Maverick is flying at 300 m/s He's being chased by Hangman, whose plane in also flying at 300 m/s. Maverick is 1200 meters ahead of hangman. Hangman theoretically shoots down mavericks plane if he can get within 250 meters of maverick ie when his position is 250 meters "less" than Maverick's position ( or if Maverick's position is 250 meters " more" than hangman's position . Hangman decides to accelerate 40 meters per second

1) how long will it take for hangman to get within shooting distance? 2) how far does hangman travel by the time he shoots down maverick?

please help me solve this problem
