Renal autoregulation is the ability of the kidneys to maintain a relatively constant GFR or glomerulofiltration rate despite fluctuating blood pressure. Autoregulation is a remarkable property of multiunit smooth muscles of small arteries and arterioles to respond to changes in internal and external pressure. The blood vessels in the human body react by contracting whenever the blood pressure is elevated and by expanding when the blood pressure is reduced. On the other hand, if there is an elevation or reduction of the external interstitial pressure, it results in dilation and contraction, respectively. The lowest autoregulating pressure is about 60 mmHg. By a further reduction in perfusion pressure, RBF is sharply reduced.

Answer:
No convention currents occur.
Explanation:
If the interior part of the Earth is cool down, it will leads to convection currents to stop. Due to this cool down of the earth's interior part cease the motion of the plates and the Earth would become geologically dead. Convection currents within the Earth's mantle occurs when the hot material rising upwards and then dropping back toward the core due to cooling so if the mantle is cool so no movement occurs as well as no convention currents.
Speed is given by dividing distance by time.
That is; speed = distance/time
In this case; speed = 52 mph and the time is 1.5 hours
Distance= speed × time
Thus; Distance = 52 × 1.5
= 78 miles
Thus the cities are 78 miles apart
