Answer: C. Student 3

Explanation: don’t you see what you marked on YOUR screen

Answer 2

Answer : The correct option is, (C) Student 3

Explanation :

Speed : It is defined as the distance covered per unit of time.

Formula used :

`Speed=(Distance)/(Time)`

From the given data we conclude that:

Speed of student 1, 2 and 3 at time 1 is:

`S_1=(1)/(1)=1`

`S_2=(2)/(1)=2`

`S_3=(4)/(1)=4`

Speed of student 1, 2 and 3 at time 2 is:

`S_1=(2)/(2)=1`

`S_2=(4)/(2)=2`

`S_3=(8)/(2)=4`

and so on.......

That means,

The speed of student 1 at time 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 is, 1

The speed of student 2 at time 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 is, 2

The speed of student 3 at time 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 is, 4

This means that, student 3 ran the fastest as student 2 and 1.
