Answer» Step-by-step explanation: let the ORIGINAL SPEED of flight be X km/he we know that time=distance/speed 6000/x - 6000/x-400= 30 by solving we get x^2-400x-4800000 x^2-2400x+2000x-4800000 x(x-2400)+2000(x-2400) (x+2000)(x-2400) x cannot be zero x=2400km/h distance/original speed = time 6000/2400 5/2hr = time I hope it will help you please mark me as BRAINLIST |
