Remember that Distance = (Average speed)(Time)
Let x be the distance between Detroit and Columbus.
We know the journey from Detroit to Columbus took a time t, and the returning trip took a time t+
. We also know the Average speed of both journeys, so now we can set our equations:
Now, we can replace equation 1 into equation 2 to find t:
Now that we know t, we can replace it into our equation 1 to get the distance:
We can conclude that the distance between Detroit and Columbus is 220 miles. <span />
