378 km

Step-by-step explanation:

To convert m/s into km/h, we multiply it by 3.6.

35 m/s x 3.6 = 126 km/h.

Distance travelled in 3 hours = 126 x 3 km = 378 km.

Marina86 [1]

Answer:

The value of x is 40.

Step-by-step explanation:

The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.

According to the angle sum property of quadrilateral, the sum of interior angles of a quadrilateral is always 360 degree.

Since the measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x, therefore

x+2x+3x+3x=360

This is the equation which is used to solve for the value of x.

9x=360

x=\frac{360}{9}

x=40

Therefore the value of x is 40.
