Final answer:
The bus travels 17.5 kilometers in 50 minutes at a speed of 21 km/hour. To find this, convert time to hours and multiply by the speed.
Step-by-step explanation:
To calculate the distance travelled by the bus, you can use the formula:
Distance = Speed × Time
First, convert the time from minutes to hours since the speed is given in km/hour:
50 minutes = 50/60 hours = 5/6 hours
Next, multiply the time by the speed to get the distance:
Distance = 21 km/h × (5/6) hours = 17.5 km
Therefore, the bus travels 17.5 kilometers in 50 minutes at a speed of 21 km/hour.
Distance can refer to the amount of space between two points or objects. It's often measured in units like meters, kilometers, miles, etc., depending on the context. In a broader sense, it can also represent a gap or emotional space between people or ideas.
