$v_{a}$ = $1.25\cdot v_{m}$

v__a =
1.25* v__m

v__a = 1.25* v__m $v_{a}$ = $1.25\cdot v_{m}$

v__a

/ 1.25

= v__m $\frac{v_{a}}{1.25}$ = $v_{m}$

v__m =

v__a

/ 1.25

$v_{m}$ = $\frac{v_{a}}{1.25}$

$v_{a}$ = $1.25\cdot v_{m}$

$\frac{v_{a}}{1.25}$ = $v_{m}$

$v_{m}$ = $\frac{v_{a}}{1.25}$

$v_{m}$ = $\frac{85}{1.25}$

$v_{m}$ = $68$
