Question: If a car travels 150 km in 3 hours, what is the percentage of speed if the average speed is 50 km/h?

Options:

Correct Answer: 100%

Solution:

Average speed = 150 km / 3 h = 50 km/h. Percentage of average speed = (50/50) * 100 = 100%.

If a car travels 150 km in 3 hours, what is the percentage of speed if the average speed is 50 km/h?

If a car travels 150 km in 3 hours, what is the percentage of speed if the average speed is 50 km/h?

Step 1: Calculate the average speed of the car by dividing the total distance traveled by the total time taken. Here, the distance is 150 km and the time is 3 hours.
Step 2: Use the formula: Average speed = Total distance / Total time. So, Average speed = 150 km / 3 h = 50 km/h.
Step 3: Now, we need to find the percentage of the average speed compared to the given average speed (which is also 50 km/h).
Step 4: Use the formula for percentage: Percentage = (Actual speed / Given speed) * 100. Here, Actual speed is 50 km/h and Given speed is also 50 km/h.
Step 5: Substitute the values into the formula: Percentage = (50 / 50) * 100.
Step 6: Calculate the result: (50 / 50) = 1, and then 1 * 100 = 100%.
Step 7: Therefore, the percentage of speed is 100%.
