Unformatted text preview: months – Ian renovates at half the rate of Joe (A) Write out algebraic equaKons in terms of rI= renovaKon rate of Ian rA=renovaKon rate of Ann rJ=renovaKon rate of Joe (B)How long will it take (in months) if Joe works alone? SoluKon to (1) • Speed*Kme=Distance • Experience tells you that the distance traveled by the bike should add to the distance traveled by running. • What is unknown and wanted? vb and vr • So need two equaKons, two unknowns • What is given? –
