A bus leaves at 9 am with a group of tourists. They travel 350 km before they stop for lunch. Then they travel an additional 250 km until the end of their trip at 3 pm. What was the average speed of the bus?

Final answer:

The average speed of the bus is calculated by dividing the total distance traveled by the total time taken. Given that the bus travels 600 km in 6 hours, its average speed is 100 km/h.

Step-by-step explanation:

To calculate the average speed of the bus, we need to use the formula:

Average Speed = Total Distance ∕ Total Time

The bus travels a total distance of 350 km before lunch and an additional 250 km after lunch, which equals 600 km for the entire trip. The bus leaves at 9 am and arrives at 3 pm, meaning the total time taken for the trip is 6 hours.

Using the formula:

Average Speed = 600 km ∕ 6 h

The average speed of the bus is 100 km/h.

Average speed = Distance traveled / time taken

In this case Time taken = Difference in hours between 3 PM and 9 AM

= 6 hours

Total distance traveled = 350 km + 250 km

= 600 kilometers

So average speed = 600/6 = 100 km/hr

Average speed of bus = 27.78 m/s

So the bus's average speed = 27.78 m/s or 100 km/hr.
