To solve for $t$ in the equation $d = rt$, you need to isolate $t$. Here's how:

$d = rt$

1. Divide both sides of the equation by $r$ (assuming $r \neq 0$):

$t = \frac{d}{r}$

Thus, the solution is:

$t = \frac{d}{r}$

Here are 5 related questions to consider:

1. How can you apply this formula to find time if distance and speed are known?
2. What happens when $r = 0$ in the formula $d = rt$?
3. How does this equation relate to the concept of velocity in physics?
4. If you double the speed, how does it affect the time taken for the same distance?
5. How can you rearrange $d = rt$ to solve for $r$?

Tip: When solving for variables, ensure you perform the same operation on both sides of the equation to maintain equality.
