2 cyclists start at the same tiem from opposite ends of a course that is 45 miles long. One cyclist is riding at 14 mph and the second is riding at 16mph. How long after they begin will they meet?
The distance between them decreases at a rate 16 + 14 = 30 mph.
How long before the 45 mile separation gets reduced to 0?
45/30 = ? hours
