Given data:
Sambhu beats Kalu by 30 meters in 10 seconds.
To find:
Time taken by Sambhu to complete the race of 1200 meters.
Solution:
Let's assume that the speed of Kalu = x meters/second
As per the given data, Sambhu beats Kalu by 30 meters in 10 seconds.
Therefore, the speed of Sambhu = (30/10) meters/second = 3 meters/second
Now, to complete a race of 1200 meters, we can use the formula:
Time = Distance/Speed
Substituting the values, we get:
Time taken by Sambhu = 1200/3 = 400 seconds
But the answer is in minutes. So, we need to convert seconds into minutes.
1 minute = 60 seconds
Therefore, 400 seconds = 400/60 minutes = 6 minutes 40 seconds
Hence, the correct option is A) 6 min 30 s.
Final Answer:
Time taken by Sambhu to complete a race of 1200 meters is 6 minutes 30 seconds.
