Calculation of Time and Distance for Each Leg of the Bus Journey

To calculate the time and distance for each leg of the bus journey, we can use the formula:

Time = Distance / Speed

1. For the first leg of the journey, the bus traveled a distance of 9 km with a speed of 36 km/h. Using the formula, we can calculate the time taken for this leg:

Time = 9 km / 36 km/h = 0.25 hours

2. For the second leg of the journey, the bus traveled a distance of 27 km with a speed of 54 km/h. Using the formula, we can calculate the time taken for this leg:

Time = 27 km / 54 km/h = 0.5 hours

Total Time and Distance for the Bus Journey

To calculate the total time and distance for the entire bus journey, we can add up the time and distance for each leg:

1. Total distance = 9 km + 27 km = 36 km 2. Total time = 0.25 hours + 0.5 hours = 0.75 hours

Therefore, the bus traveled a total distance of 36 km and took a total time of 0.75 hours for the entire journey.

Conclusion

The bus traveled a distance of 9 km with a speed of 36 km/h for the first leg of the journey, and a distance of 27 km with a speed of 54 km/h for the second leg of the journey. The total distance covered by the bus was 36 km, and the total time taken for the entire journey was 0.75 hours.
