Question 369374
{{{s=d/t}}}
(Basic equation)
{{{s=2/.20}}}
(12 minutes is one-fifth of an hour, or .20 of an hour.)
{{{s=200/20}}}
(Multiply both sides of the fraction to get whole numbers.)
{{{s=10/1}}}
(Divide both sides of the fraction to simplify.)
So, Daniel ran at an average speed of 10 miles per hour.
