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.

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:

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

the answer is 48m^2!

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
