Question

An athlete X completes one round on a track in 40 seconds. Another athlete Y
completes one found in 20 seconds. If the length of one round of the track is
200 m, choose the correct option.
Statement I: Athlete X is faster than athlete Y
Statement II: The average speed of the athlete X is 5 m/s.
(A) Only I
(B) Only II
(C) Both I and II
(D) None

Answer 1

Answer:

(B) Only II

Explanation:

Given,

An athelete X completes one round track of 200m in 40seconds. Another athelete Y completes the same in 20 seconds.

Since,

Y takes less time to complete the same track.

∴ Y is faster than X.

Hence, Statement I: Athelete X is faster than Y is FALSE.

Now, for the Average speed of X is given by,

$\rm = \dfrac{Total \: distance \: travelled}{Total \: time \: taken}$

We have ,

• Total distance = 200m
• Time taken = 40 sec.

Substitute the value,

$= \dfrac{200}{40}$

$= 5$

Hence, average speed of Athelete X is 5m/s

Statement II: The average speed of Athelete X is 5m/s is TRUE!
