Question

Micah and Linda are 230 feet apart when they start walking toward one another. Linda walks twice as fast as Micah so whenever Micah travels x feet, Linda travels 2 x feet. Let x represent the number of feet Micah has traveled since he started walking toward Linda. Write an expression in terms of x to represent the total number of feet Micah and Linda have walked toward one another.

Answer 1

Answer:

D(x) = 3x

Step-by-step explanation:

Micah travels at a rate of 'x' feet over a specific period.

Linda travels at a rate of '2x' feet over that same period.

Since they are walking in opposite directions, the total distance they have walked towards one another (D) can be determined by adding both distances:

$D(x) = x+2x\\D(x) = 3x$

The expression that describes the number of feet they have walked toward one another is D(x) = 3x.
