Answer:
t = d/r
Step-by-step explanation:
d = rt
We are solving for t, so you need t alone on the left side.
Switch sides.
rt = d
t is being multiplied by r, so you need to divide the left side by r to get rid of r. You must do the same operation to both sides of an equation, so divide both sides of the equation by r.
rt/r = d/r
rt/r is simply t, so we get:
t = d/r
