Question

d=(v+b/2)t despejar b y t ??

Answer 1

$D = (v+ \frac{b}{2}) t \\ \\ Despeje \ de \ t \qquad D = (v+ \frac{b}{2}) t \\ \\ t = \frac{D}{(v+ \frac{b}{2})} \\ \\ Despeje \ de \ b \qquad D = (v+ \frac{b}{2}) t \\ \\ \frac{D}{t} = (v+ \frac{b}{2}) \\ \\ \frac{D}{t} - v = \frac{b}{2} \\ \\ (\frac{D}{t} - v) *2 =b$

Espero que te sirva, salu2!!!!
