A migrating elephant herd started moving at a rate of 6 miles per hour. One elephant stood still and was left behind. Then this stray elephant sensed danger and began running at a rate of 10 miles per hour to reach the herd. The stray caught up in 5 minutes.

Q: How long (in hours) did the stray run to catch up? How far did it run?

 

[tkhunny]

Distance = Rate * Time

Rate = 10 mph

Time = 5 min

Fix the units and you are done.

What part of this were you not seeing? You weren't distracted by the unnecessary 6 mph, were you?
