Question

Scientists estimate the rate of a wildebeest running at full speed to be 66 feet per second. Write a function rule to describe the relationship between the time, t, and the distance, d, a wildebeest travels when running at full speed.

Answer 1

The function rule that would describe the relationship between the time, t, and the distance, d, a wildebeest travels when running at full speed is (d=rt). This is distance traveled is equal to the rate times the time traveled. Therefore, the answer would be d=66t for r=66/s. 

Answer 2

Answer:

d=66 ft/s x t

Explanation:

When a wildebeest runs at full speed (66 feet per second), there are two equivalent ways to describe the relationship between time and distance traveled. The first is a function of time:

d=(66 ft/s)t

where

d=distance traveled by the wildebeest

66 ft/s = maximum speed of the wildebeest

t=time in which it travels the distance x at the speed of 66 ft/s

The second way to relate these variables is based on distance:

t=d/(66 ft/s)

where the variables are the same as in the previous equation, only that we clear "t" in function of "d".
