Question

George walks to a friend’s house. He walks 650 meters North, then realizes he walked too far. He turns around and walks 201 meters South. The entire walk takes him 23 seconds. What is his speed per second?

Answer 1

George's total distance traveled was 851 meters, and the total time taken was 23 seconds. Using the formula for speed (distance/time), George's speed is approximately 37 meters per second.

Step-by-step explanation:

The student is asking about George's speed per second during his walk to a friend’s house. To calculate this, we first need to determine the total distance George walked. George walked 650 meters north and then 201 meters south, which gives us a total distance traveled of 650 meters + 201 meters = 851 meters.

Next, we calculate George's speed using the total distance traveled and the total time taken. The formula for speed is distance divided by time, and in this case, the entire walk took 23 seconds. Therefore, George’s speed per second is 851 meters divided by 23 seconds, which is approximately 37 meters per second.
