Question 391587
A white-tailed deer is running from a black bear at 20 mph. It is 1/3 mile in front of the bear. The bear is running at 30 mph. How long will it take the bear to catch the deer? Assume both continue running at the same pace.
--------------
Deer Data:
rate = 20 mph ; time = x hrs. ; distance = 20x miles
-----
Bear Data:
rate = 30 mph ; time = x hrs. ; distance = 30x miles
----
Equation:
bear distance - deer distance = 1/3 mile
----
30x - 20x = 1/3
10x = 1/3
x = 1/30 hr.
x = (1/30)(60 minutes) = 2 minutes
