A car travels 150 km in 2 hours and then 100 km in 1 hour. What is the average speed of the car for the entire trip? (2020)
Correct Answer: 83.33 km/h
- Step 1: Calculate the total distance traveled by the car. Add the two distances together: 150 km + 100 km.
- Step 2: Calculate the total time taken for the trip. Add the two time periods together: 2 hours + 1 hour.
- Step 3: Use the total distance and total time to find the average speed. The formula is: Average Speed = Total Distance / Total Time.
- Step 4: Plug in the numbers: Average Speed = 250 km / 3 hours.
- Step 5: Calculate the average speed to get the final answer.
- 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 crucial for calculating average speed.
