the equation d=st is used to calculate distance, rate, or time, where d is the distance in yards, r is the rate in yards per minute and t is the time in minutes. consider the statements below that describe the walking rates for the three people. graph the equation that represents the rate of the fastest person. Jordan walks for 4 min and goes 200 yards. Jack walks a rate of 55 yards per minute. Lily walks 180 yards in 3 minutes.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
