Question 234741
A migrating elephant herd started moving at a rate of 6 mph.
 One elephant stood still and was left behind. 
Then this stray elephant sensed danger and began running at a rate of 10 mph to reach the herd. 
The stray elephant caught up in 5 min. How long (in hours) did the stray run to catch up?
{{{5/60}}} = .0833 hrs
:
 how far did it run?
.0833 * 10 = .833 miles
:
 Find the distance that the herd traveled while the stray ran to catch up.
.0833 * 6 = .5 miles
:
 Then write an expression for the total distance the herd traveled.
 Let x represent the distance (in miles) that the herd traveled while the stray elephant stood still.
d = x + .5 mi
:
Dist herd traveled = distance stray traveled (when he caught up)
x + .5 = .833 mi
x = .833 - .5
x = .333 mi while the stray stood still
