A.¿Cual es la velocidad media en el intervalo de tiempo de t=20 a t=25 segundos? B.¿Cual es la velocidad instantánea en t=20 segundos?¿En t=23 segundos?

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

the simplified form is
