HOBLEY Problem 1 Finding Rate of Change Using a Table Marching Band The table shows the distance a band marches Distance Marched over time. Is the rate of change in distance with respect to time constant? What does the rate of change represent? Time Distance (min) (ft) rate of change = change in distance change in time - 260 Calculate the rate of change from one row of the table to the next. 2 520 520 - 260 _ 260 780 - 520_ 260 1040 - 780 260 W 780 2 -1 3 - 2 1 4- 3 4 260 ft 1040 The rate of change is constant and equals 1 min' It represents the distance the band marches per minute
