Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

On a road trip, a family drives 350 miles per day. How many days, d, must they travel to reach a distance of at least 1,400 miles

What does the solution represent in this situation

A. d ≥ 4; The family must travel at least 4 days.

B. d ≤ 4; The family must travel 4 or more days.

C. d < 4; The family must stop fewer than 4 times per day.

D. d > 4 ; The family must travel more than 4 miles per day.

EVALUATION

Here it is given that On a road trip, a family drives 350 miles per day.

Now they have to travel to reach a distance of at least 1,400 mile

Let d be the required number of days

Then the distance travelled in d days

= 350d miles

So by the given condition

$\sf{350d \geqslant 1400}$

$\sf{ \implies \: d \geqslant 4}$

So the family must travel at least 4 days

FINAL ANSWER

Hence the correct option is

A. d ≥ 4 ; The family must travel at least 4 days.
