: : : I am struggling with Algebra and my brain just can't handle word problems. Help is appreciated. : : : With the wind, a quarterback passes a football 140 feet in 2 seconds. Against the wind, the same pass would have traveled 80 feet in 2 seconds. Find the rate of the pass and the rate of the wind. : : : I'm thinking... (since d=r.t) : : : 140=R.2 : : : 80=R.2 : : : If so, why can't I come up with a logical answer? : : ******************************************* : : 1) What do you want to find (unknowns)? 2 unknowns: : : the rate of the pass = P......and : : the rate of the wind = W : : 2) What are given: distance and time (Your choice of equation is correct) : : 3) With the wind: Rate= P + W : : 140 = (P +W)*2 : : 4) Against the wind: Rate = P - W : : 80 = (P-W)*2 : : 5) In (3) and (4) you have two equations and two unknowns - solve it....
