Answer 1

Answer:

83.3m/s

Explanation:

speed=distance/time

distance=750+250=1000mts

time=13s

Answer 2

Answer:

76.923m/s

Explanation:

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?

d1=750  

d2=250                                                

t=13                                                      

s=?                                                                    

FORMULA:

speed= distance ÷ time ( 750m + 250m =1000m ÷ 13s =76.923 )                                                            

MORE EXPLANATION:

750m + 250m = 1000m

So, he walked 1000m in 13 seconds.   ( =1000÷ 13 )

To find the rate per second, simply divide the distance by the time.

1000m ÷ 13seconds = 76.923m/s

NOTE: trust me it is the true answer :) Goodluck
