Given a speed of 12.5 m/s and a time of 55 seconds how far would the object travel

687.5 m

Explanation:

as the given speed (or velocity) is given as 12.5 m/s and time is 55 sec...

then total distance to be travelled in 55 secs= (12.5× 55) m = 687.5 m

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.
