Answer:
50 km/h
Explanation:
The average speed of the car is essentially the same thing as the unit rate.
Here a car goes 300 km for every 6 hours. To find the unit rate, we must find how many kilometers it goes per hour.
To do so, we can divide 300 by 6 to get a total of 50km/h.
Answer:
The pumping of the heart involves the alternate contraction and relaxation of the chambers of the heart. The upper chambers of the heart are called at atria and the lower chambers of the heart are called ventricles.
The statements that are true for S-waves are:
A. They can only travel through the solid rock inside Earth.
C. They are the second type of waves detected after an earthquake.
The S-wave is the second wave that gets detected by the seismograph. These waves do not travel through the liquid medium. They are also slower than the initially detected P-waves. S-wave also are more destructive than the P-waves but are relatively less destructive than the L-waves and the Rayleigh waves.
Answer B sounds reasonable
