Question
Delhi is at a distance of 200 km from Ambala. A sets out from Ambala at a speed of 30 km/h and B sets out at the same time from Delhi at a speed of 20 km/h. When they will meet each other ?
Solution
Sure, let's solve this step by step:
Step 1: Understand the problem A is traveling from Ambala to Delhi at a speed of 30 km/h. B is traveling from Delhi to Ambala at a speed of 20 km/h. They start at the same time. We need to find out when they will meet each other.
Step 2: Calculate the relative speed When two objects move towards each other, their relative speed is the sum of their individual speeds. So, the relative speed of A and B is 30 km/h + 20 km/h = 50 km/h.
Step 3: Calculate the time they will meet The time it takes for two objects to meet when they are moving towards each other can be found by dividing the total distance by the relative speed. So, the time it will take for A and B to meet is 200 km / 50 km/h = 4 hours.
So, A and B will meet each other 4 hours after they start their journey.
