Triangle PMT is shown below

option 1

Step-by-step explanation:

If line segment TK is a straight line then is a both median and altitude of triangle PMT.

If Tk is a straight line, then ΔTKP & ΔTKM are congruent triangle by A S A congruent. So, KP = KM  {CPCT}.

Tk is a median

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
