According to the distance formula:
+d=rt+
We can assume from the problem that
+d+=+3+
+t+=+4+
So, we plug in the distance and time into the formula to find the rate first.
+3+=+r%284%29+
+3%2F4+=+r+ Division Property of Equality
So if r = 3/4, then we can also plug in the time of 7 minutes into the equation to find the distance traveled in 7 minutes.
+d+=+%283%2F4%29%287%29+
+d+=+21%2F4+ Simplify
