Solve for d
d=\frac{t\left(u+v\right)}{60}
u\neq -v
Solve for t
t=\frac{60d}{u+v}
u\neq -v

t\left(u+v\right)=60d
Multiply both sides of the equation by u+v.
tu+tv=60d
Use the distributive property to multiply t by u+v.
60d=tu+tv
Swap sides so that all variable terms are on the left hand side.
\frac{60d}{60}=\frac{t\left(u+v\right)}{60}
Divide both sides by 60.
d=\frac{t\left(u+v\right)}{60}
Dividing by 60 undoes the multiplication by 60.
