Question

George walks to a friend's house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his speed per second to the first decimal point?

Answer 1

76.9 m/s

Step-by-step explanation:

total distance travelled is 750m + 250m = 1000m

the total time taken is 13 seconds.

1000m/13s = 76.9 m/s (1dp)
