How to Calculate Speed of an ObjectYour Subtitle Goes Here

Put in a Linear Formula (Distance Formula)

y=mx+b

y=10x+b

y=10x+0

D=10x+0

D=10(T)+0

D=10(T)

D=S(T)

Distance= Speed* Time

Speed Formula

D=S(T)

D=S(T)

TT

D=S

T

Speed = Distance Time

Time Formula

D=S(T)

SS

D=T

S

Time = Distance Speed
