Answer 1

Answer:

mark brainliest

Step-by-step explanation:

taking ABC as a right angled triangle

AB = 240,(height),AO=320(base) then BO (height) =?

according to Pythagoras law

${ob}^{2} = {ao}^{2} + {ab}^{2} \\ {ob}^{2} = {320}^{2} + {240 }^{2} \\ {ob}^{2} = 102400 + 57600 \\ {ob}^{2} = 160000 \\ ob = \sqrt{160000} \\ ob = 400$

hence, the shortest distance covered by plane to reach its original position is 400 kilometer.
