Maths for data science - WEEK 2 , ques num 3

[gamer 110]

Hello,

The equation for the line being y= -2/3x+60 and the values of x being substituted to get the value y , we get the intersection points , with which we find whether the person standing at that point is in the path of the bullet . 

The solution given has stated person M to be in the path of the bullet . When the value of x is substituted as 90 , which is the point at which person L stands , we get the value of y to be 0. 

This solution implies that the path of the bullet ends at (90,0) which is exactly where person L is standing , which means the bullet may hit the feet of the person , as his feet are planted at the point (90,0) . This in turn would mean person L will not be safe  . 

Can you please check whether this explanation stands and can be considered ?

Who/where else can I approach to clear this doubt?

You are perfectly right and many of us have done the same. But they that bullet will not penetrate. How to assume that. The Question itself is wrong

[Jaysingh Magar]

You explained correctly. Bullet may penetrate human body if considered in reality & can follow same straight line path & hit exact point where L is standing.
