How many minutes will it take Graham and Max to meet at the same altitude?a. Equation:__________________b. Solution:__________________c. At what altitude will Graham and Max meet?______________ |
|
Answer» Solution :- Graham :-
14040 , 13990, 13940, __________ = form an AP. Max :-
12500 , 12520, 12540, __________ = form an AP . Let us Assume that , after n minutes Graham and max meet at the same altitude . Than, → in n minutes Graham will be at an altitude of = a + (n - 1)d = 14040 + (n - 1)(-50) { Descending .} → in n minutes Max will be at an altitude of = a + (n - 1)d = 12500 + (n - 1)20 a) → 14040 + (n - 1)(-50) = 12500 + (n - 1)20 b) → 14040 - 50N + 50 = 12500 + 20n - 20 → 14090 - 50n = 12480 + 20n → 20n + 50n = 14090 - 12480 → 70n = 1610 → n = 23 minutes. (Ans.) c) → Altitude where graham and max meet = 12500 + (n - 1)20 = 12500 + (23 - 1)20 = 12500 + 22*20 = 12500 + 440 = 12940 feet . (Ans.)
