Question: If a car travels 100 m in the first 5 seconds and 150 m in the next 5 seconds, what is its average speed over the 10 seconds?

Options:

Correct Answer: 30 m/s

Solution:

Total distance = 100 m + 150 m = 250 m. Total time = 10 s. Average speed = total distance / total time = 250 m / 10 s = 25 m/s.

If a car travels 100 m in the first 5 seconds and 150 m in the next 5 seconds, what is its average speed over the 10 seconds?

If a car travels 100 m in the first 5 seconds and 150 m in the next 5 seconds, what is its average speed over the 10 seconds?

Step 1: Find the distance traveled in the first 5 seconds, which is 100 meters.
Step 2: Find the distance traveled in the next 5 seconds, which is 150 meters.
Step 3: Add the two distances together: 100 m + 150 m = 250 m.
Step 4: Find the total time taken, which is 5 seconds + 5 seconds = 10 seconds.
Step 5: Calculate the average speed by dividing the total distance by the total time: 250 m / 10 s.
Step 6: The average speed is 25 meters per second (m/s).

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