Question

3. A bus takes 2 hours to reach from station A to station B, and then 3 hours to return from station B to station A. Find the average velocity of the bus, if the distance between station A and station B is 50 kilometres.​

Answer 1

20 km/hour

Step-by-step explanation:

The average velocity of the bus is given by the total distance traveled divided by the total time taken.

Let's first calculate the total distance traveled by the bus. The distance between station A and station B is 50 kilometers. The bus travels this distance twice, once from A to B and then from B to A. Therefore, the total distance traveled by the bus is:

Total distance = 2 x 50 km = 100 km

Now, let's calculate the total time taken by the bus. The bus takes 2 hours to travel from A to B and 3 hours to travel from B to A. Therefore, the total time taken by the bus is:

Total time = 2 hours + 3 hours = 5 hours

Now we can use the formula for average velocity to find the answer:

Average velocity = Total distance / Total time

Substituting the values we calculated, we get:

Average velocity = 100 km / 5 hours = 20 km/hour
