Respuesta :

The fraction would probably be the speed as well so here:

You do 20/45 which simplifies to 4/9

So the speed/fraction for this problem is 4/9 (feet per second)


P.S. I'm sorry if this is hard to understand

20ft = 45 sec

divide both by 5 you get

4ft = 9 sec

4ft every 9 seconds would be your answer unless you want a fraction.

1 ft = 2 1/4 seconds

I hope I helped. If you think I'm worthy a Brainliest answer would be nice :D
