You can put this solution on YOUR website!
Her rate is:
+24%2F1+ mi/hr
----------------
Note that +20+ min = +1%2F3+ hr
You could set up a ratio:
+24%2F1+=+d%2F%28%28+1%2F3+%29%29+
----------------------
Multiply top and bottom of the right side by +3+
+24%2F1+=+3d+
Divide both sides by +3+
+d+=+8+
She could drive 8 miles in 20 min
---------------
check:
In 3 times that amount of time, she
could drive 3 times as far, so
In 60 min she could drive 24 miles
or, 24 mi/hr
OK
