We have that, how long it will take for Liu to catch Mariel is mathematically given as
t=3.076s
From the question we are told
Mariel and Liu are running a long-distance race. Mariel runs at a rate of 5.4 m/s, and Liu runs at a rate of 7.6 m/s. If Mariel has a 20 m head start, how long will it take for Liu to catch Mariel?
Generally the equation for the Average speed is mathematically given as

Therefore
How long it will take for Liu to catch Mariel is mathematically given as

t=3.076s

B.
Because it reflects over
Answer:
None
Step-by-step explanation:
The average rate of change of a function f(x) over an interval (a, b) is given by

Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
