In 1/12 hour at 10 miles per hour the elephant ran 10/12=5/6 miles
The herd was travelling at 6 miles per hour, so in the 1/12 hour the stray2. find the distance that the herd traveled while the stray ran to cacth up.let x represent the distance that the herd traveled while the stray elephant stood still.
was running it travelled 6/12=1/2 mile.
The distance the herd travelled while the stray stood still x=5/6-1/2=1/3 mile.
So the time that the stray stood still was the time it took the herd to
travel 1/3 mile at 6 miles per hour, which is (1/3)/6=1/18 hour=3 1/3 minutes
or 3 min 20s.
