Answer:

The time is less than or equal to 1.5 hours

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

$(105)/(x)\leq 70$

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
