Two cyclists, 68 miles apart, start riding toward each other at the same time. One cycles 3 miles per hour faster than the other, and they meet after 4 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. b. What are the speeds of the two cyclists?

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

part a: 1.08

part b: 27.59

there are infinitely many solutions.

it should be a.

hope it
