7-96.

Use a proportion to solve the problem.

$\frac{3}{4}=\frac{x}{1}$

x = 0.75

Write the equations for each rider based on the given information.
Dean: y = 0.75x + 5
Carlos: write a similar equation.

Set the equations equal to each other and solve for x. Then substitute x back into one
of the original equations to solve for the distance from the starting line.
