Distance between A & B is 550 km. Both start walking towards each other with the speed of 60 km/h and 50 km/h respectively. Find the time taken by them to meet each other.

Answer

To solve the problem, we need to find the time taken for two people walking towards each other to meet. Here’s a step-by-step solution:

### Step 1: Identify the given information
- Distance between A and B = 550 km
- Speed of person A = 60 km/h
- Speed of person B = 50 km/h

### Step 2: Calculate the combined speed
When two objects move towards each other, their speeds add up. Therefore, we calculate the combined speed as follows:

\[ \text{Combined Speed} = \text{Speed of A} + \text{Speed of B} \]
\[ \text{Combined Speed} = 60 \text{ km/h} + 50 \text{ km/h} = 110 \text{ km/h} \]

### Step 3: Use the formula to calculate time
The formula to calculate time when distance and speed are known is:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Now, we can substitute the values into the formula:

\[ \text{Time} = \frac{550 \text{ km}}{110 \text{ km/h}} \]

### Step 4: Perform the calculation
\[ \text{Time} = 5 \text{ hours} \]

### Conclusion
The time taken by A and B to meet each other is **5 hours**.
