Answer 1

The horizontal distance is 11.25 meters.

Step-by-step explanation:

Step 1:

The gradient of the given road is $\frac{4}{15}$. The gradient is the ratio of the difference in y values to the difference in x values.

In the given diagram, the difference in y values is given as 3 meters.

The difference in x values is given as x meters.

So if we substitute it with the gradient, we can determine the values of x.

Step 2:

The gradient, $\frac{4}{15} = \frac{3}{x},$ by cross-multiplying we get

$x = (3)(\frac{15}{4} ) = \frac{45}{4} = 11.25.$

So the horizontal distance is 11.25 meters.
