A person walks 5 km in 1 hour and then runs 10 km in 1 hour. What is the average speed for the entire journey? (2022)

A person walks 5 km in 1 hour and then runs 10 km in 1 hour. What is the average speed for the entire journey? (2022)

Step 1: Calculate the total distance traveled. The person walks 5 km and then runs 10 km. So, total distance = 5 km + 10 km.
Step 2: Add the distances together. Total distance = 5 km + 10 km = 15 km.
Step 3: Calculate the total time taken. The person walks for 1 hour and runs for 1 hour. So, total time = 1 hour + 1 hour.
Step 4: Add the times together. Total time = 1 hour + 1 hour = 2 hours.
Step 5: Calculate the average speed. Average speed = Total distance / Total time.
Step 6: Substitute the values into the formula. Average speed = 15 km / 2 hours.
Step 7: Perform the division. Average speed = 7.5 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 crucial for solving average speed problems.
