If the Sun’s 1,395,000 km diameter is shrunken down to 12 inches, and the next closest star is 4.20 × 1013 km from the Sun, how far apart should the two be placed in a properly scaled model of the Sun and its nearest neighbor, Proxima Centauri? (For your answer, convert the scale model distance into miles, since the separation in inches will be huge)

30,179,400 miles
340 miles
362,152,200 miles
2.295×1013 miles
5720 miles
30,107,500 miles
68,590 miles
Human beings have not evolved to the point where inches can be converted into miles

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
