To find the distance \( d \) that Chloe drove in miles based on the time \( t \) in hours, we can use the equation for distance, which is given by the formula:
\[ d = r \cdot t \]
where \( r \) represents the rate of speed in miles per hour.
If Chloe drove at a rate of 50 miles per hour, we can substitute \( r \) with 50:
\[ d = 50t \]
So the equation to find the distance \( d \) that Chloe drove in miles if she drove for \( t \) hours is:
\[ d = 50t \]
This means Chloe's distance in miles can be calculated by multiplying the time she drove in hours (\( t \)) by the speed she drove, which is 50 miles per hour.
