Answer 1

Total answer is (5,22.5)

Answer 2

From the given instruction, we observed that Niharika posted the green flag at 1/4th of the distance AD i.e., (1/4 ×100) m = 25m from the starting point of 2nd line. Therefore, the coordinates of this point are (2, 25).

Similarly, Preet posted red flag at 1/5 of the distance AD i.e., (1/5 ×100) m = 20m from the starting point of 8th line. Therefore, the coordinates of this point are (8, 20).

Distance between these flags can be calculated by using distance formula,

The point at which Rashmi should post her blue flag is the mid- point of the line joining these points. Let say this point be P(x, y).

x = (2+8)/2 = 10/2 = 5 and y = (20+25)/2 = 45/2

Hence, P( x, y) = (5,45/2)

Therefore, Rashmi should post her blue flag at 45/2 = 22.5m on 5th line.
