\[d = rt\]
We know \(d = 160\text{ miles}\) and \(r = 32\text{ miles/hour}\) so \(t\) is the missing variable. To solve for \(t\), we divide both sides of the equation by \(r\), giving us:
\[\frac{d}{r} = \frac{rt}{r} \]\[t = \frac{d}{r}\]Now plug in the known values of \(d\) and \(r\) to find the value of \(t\).

\[t = \frac{d}{r} = \frac{160}{32}=\]Can you divide 160 by 32?

What does 32+32=
What does 32+32+32=
What does 32+32+32+32=
What does 32+32+32+32+32=
That should give you a hint about the answer...

no. 160/32 = ?
how many 32s did you have to add up to get 160?
