Answer : The correct option is, (C) Student 3
Explanation :
Speed : It is defined as the distance covered per unit of time.
Formula used :
[tex]Speed=\frac{Distance}{Time}[/tex]
From the given data we conclude that:
Speed of student 1, 2 and 3 at time 1 is:
[tex]S_1=\frac{1}{1}=1[/tex]
[tex]S_2=\frac{2}{1}=2[/tex]
[tex]S_3=\frac{4}{1}=4[/tex]
Speed of student 1, 2 and 3 at time 2 is:
[tex]S_1=\frac{2}{2}=1[/tex]
[tex]S_2=\frac{4}{2}=2[/tex]
[tex]S_3=\frac{8}{2}=4[/tex]
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.
