The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function h (t) = 300 minus 16 t squared. Which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall?

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
