If a bus travelled 300 km in $7\frac{1}{2}$  hours with uniform speed, then the number of kilometers it travelled in 1 hour is

Solution:

To calculate the distance traveled in 1 hour, divide the total distance by the total time:

• Total distance: 300 km
• Total time: 7 1/2 hours = 7.5 hours

Using the formula:

Speed = Distance ÷ Time

Substituting the values: 
Speed = 300 ÷ 7.5 = 40 km/h

Final Answer

The bus travels uniformly at a speed of 40 km per hour. This is obtained by dividing the total distance (300 km) by the total time (7.5 hours).
