Question

The speed limit on highways in Florida is 70 miles per hour write and solve an inequality to find how long it will take to travel 105 miles from Orlando to St Augustine if you travel at or below the speed limit

Answer 1

Answer:

The time is less than or equal to 1.5 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the time in hours

The inequality that represent this situation is equal to

$\frac{105}{x}\leq 70$

Solve for x

Multiply by x both sides

$105 \leq 70x$

Divide by 70 both sides

$105/70 \leq x$

Rewrite the inequality

$x \geq 105/70$

$x \geq 1.5\ hours$

therefore

The time is less than or equal to 1.5 hours
