Walking on his own, the distance, D, in feet, that Roberto can cover in m minutes is given by the function D(m)=264m. When he walks on the moving sidewalk at the airport, the distance, A, in feet, that he can cover in m minutes is given by the functionA(m)=440m. Let B be the distance, in feet, that Roberto would travel on the moving sidewalk in m minutes if he were standing still.Write a formula for B(m) in terms of D(m) and A(m).B(m)=Write a formula for B(m) in terms of m.B(m)=□ Get tutor help
