Segment PR has endpoints P(-8,-1) and R(4,2). Point Q lies on 1
segment PR such that QR = 3 PR. What are the coordinates of point Q?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Not sure what the question is but i hope this x = years100 * x
