Question

PLEASE HELP ME!!!

On a road trip a family drives 350 miles per day how many days D must they travel to reach the distance of at least 1400. Solve the inequality what does the solution represent in this situation?
(Just in case you wanted to see the question I put a picture)

Answer 1

`350 * D \geq 1400`

`D\ge 4`

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

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 greater than or equal to]

`350 * D \geq 1400`

Divide through by 350

`(350 * D)/(350) \ge (1400)/(350)`

`D \ge (1400)/(350)`

`D\ge 4`

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