Question A train leaves the station at time t=0. Traveling at a constant speed, the train travels 420 kilometers in 3 hours. Answer parts a and b.

Answer: f(t) = 160t, d = f(t) The function that relates the distance traveled d to the time t is: f(t) = 160t, where d = f(t) Step-by-step explanation: If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour: d = 160t Now we replace d by f(t) because d = f(t): f(t) = 160t for any given value of t, d will be equal to t multiplied 160 times Reply
