IPMAT Indore 2022 - QA (MCQ) Q26 Explanation
December 28, 2024
Explanation:
(c)
Let the speed of Ashok, Bipin and Chandan be a, b and c m/s.
As per the question,
Bipin can cover 150m in 15 sec.
∴ His speed,b = 150/15 = 10 m/s.
Also, difference in the time taken by Bipin and Ashok to reach the finishing line is 15 sec.
∴ 400/10 − 400/a = 15
∴ a = 16m/s
Also 400/c − 400/16 = 25
∴ c = 8 m/s
Now, the ratio of distance travelled by Bipin and Chandan will be in the ratio of their speeds, as the distance travelled by them is same.
So, 400/x = 10/8 ⇒ x=320
Therefore, Bipin will beat Chandan by 80m.
