distance=rate*time

anonymous · Answer

so we solve for rate first? @JoannaBlackwelder

joannablackwelder · Answer

We are given rate. We are looking for time. So, solve for time.

Can u help me with that please @JoannaBlackwelder

joannablackwelder · Answer

|dw:1439920734718:dw| To solve for time, we need to get it by itself.

joannablackwelder · Answer

|dw:1439920766408:dw| r is currently multiplied by t, so we divide by it to get rid of it on that side. And what we do to one side of an equation, we have to do to the other side.
