vavg = s / t

The formula for s becomes;

The formula for s becomes;

A

s = vavg/ t

B

s = vavg x t

C

s = t / vavg

D

s= t x vavg

vavg = s / t

The formula for t becomes;

The formula for t becomes;

A

t = vavg/ s

B

t = vavg x s

C

t = s / vavg

D

t = s x vavg

vavg = vstart + vfinal / 2

The formula for vstart becomes;

The formula for vstart becomes;

A

vstart = vavg / 2 - v final

B

vstart = vavg x 2 - v final

C

vstart = vavg / 2 + v final

D

vstart = vavg x 2 + v final

vavg = vstart + vfinal / 2

The formula for vfinal becomes;

The formula for vfinal becomes;

A

vfinal= vavg / 2 - vstart

B

vfinal = vavg x 2 - vstart

C

vfinal= vavg / 2 + vstart

D

vfinal = vavg x 2 + vstart l
