Question: A bus travels 120 km in 2 hours and then 180 km in 3 hours. What is the average speed of the bus? (2023)

Options:

Correct Answer: 75 km/h

Exam Year: 2023

Solution:

Total distance = 120 + 180 = 300 km. Total time = 2 + 3 = 5 hours. Average speed = 300 km / 5 hours = 60 km/h.

A bus travels 120 km in 2 hours and then 180 km in 3 hours. What is the average speed of the bus? (2023)

Step 1: Find the total distance traveled by the bus. Add the two distances: 120 km + 180 km.
Step 2: Calculate the total distance: 120 + 180 = 300 km.
Step 3: Find the total time taken by the bus. Add the two times: 2 hours + 3 hours.
Step 4: Calculate the total time: 2 + 3 = 5 hours.
Step 5: Calculate the average speed. Use the formula: Average speed = Total distance / Total time.
Step 6: Plug in the values: Average speed = 300 km / 5 hours.
Step 7: Calculate the average speed: 300 / 5 = 60 km/h.

Average Speed – Average speed is calculated by dividing the total distance traveled by the total time taken.
Distance and Time Calculation – Understanding how to sum distances and times correctly is essential for calculating average speed.
