Question 100667
When the stray elephant caught it, it had traveled the same distance as the herd. Otherwise, it would not have caught up with them. (Right?)

Therefore, the herd had to have walked .83 of a mile.  At 6 miles per hr, the herd  covers 1 mile every 10 minutes. So they had walked for 8.3 minutes at 6 miles per hour to cover .83 miles.

Think of the basic equation: d = r * t.  Distance = Rate * Time.  We know the herd traveled .83 miles and that they traveled at 6 miles/hr.  So we divide .83 by 6 and get .138333 hours. Times 60 min/hr, we get 8.3 minutes.

With a problem like this one, it is a good idea to get everything into the right units of measure. Then looking at the units of measure you need in your answer should help you decide what to do next.

So, the equation for the distance traveled would be: d = 6 mi/hr * .138333 hr.
