A bus takes 30 minutes to travel a distance of 25 kilometres. Calculate the speed of the bus in `km//h`.

Answer

To calculate the speed of the bus in kilometers per hour (km/h), we can follow these steps:

### Step 1: Identify the given values
- Distance traveled by the bus = 25 kilometers
- Time taken = 30 minutes

### Step 2: Convert the time from minutes to hours
Since speed is typically calculated in kilometers per hour, we need to convert the time from minutes to hours.
- 30 minutes = 30/60 hours = 0.5 hours

### Step 3: Use the speed formula
The formula for speed is given by:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

### Step 4: Substitute the values into the formula
Now we can substitute the distance and time into the formula:
\[ \text{Speed} = \frac{25 \text{ km}}{0.5 \text{ hours}} \]

### Step 5: Calculate the speed
Now perform the division:
\[ \text{Speed} = 25 \div 0.5 = 50 \text{ km/h} \]

### Final Answer
The speed of the bus is 50 km/h.
