The ratio of the two is a number without units because "inches" in the numerator and denominator would cancel.<br /><br />The athlete is in feet and inches, which gets converted to feet, and the distance the athlete wants to cover is in miles, which also gets converted to feet, so that two can be compared as a ratio. Again, the ratio will have no units.<br /><br />You don't need to convert either the athlete or the mile into inches. You could, but it would just make unnecessarily big numbers, which would just cancel anyway.<br /><br />TL;DR: The grasshopper jumps twenty times its body length. If a 69-inch human jumped twenty times its body length, he/she would jump 1380 inches, or 115 feet. Four such jumps would be 5520 inches or 460 feet. That would be less than one-tenth of a mile.<br /><br />Had you done all the work, and then divided by 12, you would have lost a one point for making a conceptual error.<br /><br />I hope this helps.(x, why?)https://www.blogger.com/profile/17499160002806879025noreply@blogger.comtag:blogger.com,1999:blog-28172905.post-85441165059262010712018-05-31T20:14:48.791-04:002018-05-31T20:14:48.791-04:00Question 30 is incorrect, the height needs to be c...Question 30 is incorrect, the height needs to be converted to inches because the grasshoppers length is in inches.
