Two cyclists, 55 miles apart, start riding toward each other at the same time. One cycles 5 miles per hour faster than the other
, and they meet after 5 hours of riding. a. Write an equation using the information as it is given above that can be solved to answer this problem. Use the variable r to represent the speed of the slower cyclist.
The first term occurs when . Next the second term occurs when , the third term when and so on. Therefore, the appropriate value of n that lies on the domain for n is
