Mathematics

Answer:

Step-by-step explanation:

The minimum is at the vertex of this parabola because it opens up.

Now if (-4, 2) is the minimum then  all the y values on the parabola must be > 2,

But we are given that  y = -3 is on the graph ( the point (6,-3) - that is y < 2 here,

Therefore (-4, 2)  cannot be the vertex .

<u>We are given:</u>Distance covered by the fastest man in 9 seconds = 100m

<u>To Find: </u>The distance covered in 1 min 2 seconds or 62 seconds

<u>Finding the Speed of the man:</u>

We know that:

speed = distance covered / time taken

Speed = 100 / 9          <em>(we are given that he travels 100 m in 9 seconds)</em>

Speed = 11.11 m/s

<u>Distance travelled in 62 seconds:</u>

We know that:

distance covered = speed * time

<em>replacing the value of speed and time</em>

Distance = 11.11 * 62

Distance = 688.82 m
