PLEASE HELP ME!!!

Answer:

350 * D \geq 1400

D\ge 4

This means that the family must travel for at least 4 days.

<em></em>

Step-by-step explanation:

Given

Rate = 350\ miles\ daily

Distance = 1400\ miles\ (atleast)

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

350 * D \geq 1400

[The term "At least" is used to represent <em>greater than or equal to</em>]

350 * D \geq 1400

Divide through by 350

\frac{350 * D}{350} \ge \frac{1400}{350}

D \ge \frac{1400}{350}

D\ge 4

<em>This means that the family must travel for at least 4 days.</em>
