Wind is air in motion. Two factors are necessary to specify wind, speed and direction. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Because of the way Earth rotates, solar light rays heat some parts of Earth's surface more than others. Air at hot spots rises and expands, leaving low pressure beneath it. Air at cold areas cools and falls, creating high pressure. When high-pressure air rushes into a low pressure area, that rush of air is wind.
Answer:
Approximately 3771 times
Step-by-step explanation:
Let x be the number of times the wheels turn in 5 miles.
Given that, 1mile = 5,280ft
Thus, 5 miles=5 × 5,280ft=26400ft
From the question ,we can deduce the following ratios :
140 ft : 20 mins
26400ft : x
Cross multiply;
Divide through by 140.
THEN LET IT MAKE A SANDWICH
