Help! Giving brainliest and 10+ points, A ball is dropped from the top of a 400-ft tall tower. The relationship between the time
, t, in seconds, and the height, h(t), in feet, of the ball can be modeled by a quadratic function. Specific values of the function are shown in the table below
Part A: Determine the average rate of change of h(t) between t = 2 and t = 5.
Part B:Explain what this average rate of change means in terms of the context.

Answer:
Speed of car B is 33 km/h and speed of car A is
Step-by-step explanation:
Let speed of car B be km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = km =
km
Distance travelled by car B in 4 hours = km
Also, cars A and B are 312km apart after 4 hours.
Speed of car B is 33 km/h and speed of car A is
