PLEAS HELP I REALLY NEED HELP!! LOTS OF POINTS 5. Diego says d=3t that represents his walk, where is the distance walked in miles and is the time in
hours.
a. Explain why d=3t relates the distance Diego walked to the time it took.
b. Write two equations that relate distance and time: one for Elena and one for Andre.
6. Use the equations you wrote to predict how far each participant would walk, at their same rate, in 8
hours.
7. For Diego's equation and the equations you wrote, which is the dependent variable and which is the
independent variable?
