Given information:
Krishna and Kamlesh are on a straight road.
Kamlesh took 3 hours more than Krishna to cover 30 km.
If Kamlesh doubles his speed, he is ahead of Krishna by 3 by 2.
Let's solve the problem step by step:
Step 1: Determine the speeds of Krishna and Kamlesh
Let the speed of Krishna be x km/hr.
Then, the speed of Kamlesh would be (x + 30/3) km/hr = (x + 10) km/hr.
Step 2: Formulate the equation based on the given information
According to the second statement, when Kamlesh doubles his speed, he is ahead of Krishna by 3 by 2.
So, the equation can be written as:
30 / x = 30 / (x + 10) + 3
Step 3: Solve the equation to find Krishna's walking speed
Solving the above equation, we get:
30 / x = 30 / (x + 10) + 3
30(x + 10) = 30x + 3x(x + 10)
30x + 300 = 30x + 3x^2 + 30x
3x^2 - 300 = 0
x^2 - 100 = 0
(x + 10)(x - 10) = 0
x = 10 (neglecting negative value)
Therefore, Krishna's walking speed is 10 km/hr.
Conclusion:
Krishna's walking speed is 10 km/hr.
Krishna and Kamlesh are on a straight road.
Kamlesh took 3 hours more than Krishna to cover 30 km.
If Kamlesh doubles his speed, he is ahead of Krishna by 3 by 2.
Let's solve the problem step by step:
Step 1: Determine the speeds of Krishna and Kamlesh
Let the speed of Krishna be x km/hr.
Then, the speed of Kamlesh would be (x + 30/3) km/hr = (x + 10) km/hr.
Step 2: Formulate the equation based on the given information
According to the second statement, when Kamlesh doubles his speed, he is ahead of Krishna by 3 by 2.
So, the equation can be written as:
30 / x = 30 / (x + 10) + 3
Step 3: Solve the equation to find Krishna's walking speed
Solving the above equation, we get:
30 / x = 30 / (x + 10) + 3
30(x + 10) = 30x + 3x(x + 10)
30x + 300 = 30x + 3x^2 + 30x
3x^2 - 300 = 0
x^2 - 100 = 0
(x + 10)(x - 10) = 0
x = 10 (neglecting negative value)
Therefore, Krishna's walking speed is 10 km/hr.
Conclusion:
Krishna's walking speed is 10 km/hr.
