d = distance traveled by her on her bicycle on a long flat road = 24 kilometer

t = time taken by her to travel distance "d" on her bicycle on a long flat road = 1.2 hours

v = average speed of vivian = ?

we know that average speed is given as

v = d/t

inserting the values in the above formula

v = 24 kilometer / 1.2 hour

v = 20 kilometer/hour


hence the correct choice is

C) 20 km/h

A plane glides towards a ground-based radar dish. Radar locates the plane at a distance D = 22 km from the dish, at an angle θ =
vfiekz [6]

The correct answer is :

Unit vectors I and j along the x-axis and y-axis, respectively, define the Cartesian coordinate system. The radial unit vector r, which indicates the direction from the origin, and the unit vector t, which is orthogonal (perpendicular) to the radial direction, together create the polar coordinate system.

We can obtain the horizontal component by applying the trigonometric identity of Cos(Ф), and if we obtain the component on the x axle, such as 22000 (m)×Cos(51°) = x, we may determine that x = 13845.05 metres. We need to obtain the vector components because we already know the distance and the angle.

Mildred takes a pound of frozen hamburger meat out of the freezer and puts it into the refrigerator.
Hatshy [7]
The meat in the freezer is frozen. 
Everything else in the freezer is frozen too. 
Nothing in the refrigerator is frozen. 
The freezer is colder than the refrigerator.  <span>

Mildred takes a pound of frozen hamburger meat out of the freezer
and puts it into the refrigerator.  The meat is colder than anything
else that's in there.

Heat flows from the air in the refrigerator into the frozen hamburger (C)
and warms up the meat.  When the temperature of the meat warms up
to the temperature of the air in the refrigerator, the heat stops flowing.</span>
