Answer:
Maximum speed of bird A is
Maximum speed of bird B is
Step-by-step explanation:
This is a problem with two unknowns: Max speed of bird A (we name that "A"), and max speed of bird B (we call that "B"). Now we can create two equations with these two unknowns, based on the info provided:
Equation 1): based on the phrase "bird A can travel six times as fast as bird B" we write:
Equation 2): based on the phrase; "the total speeds for these two birds is 224 miles per hour", we write:
Now, we use the first equation to substitute A in the second equation, ad then solve for the unknown B:
Now we can solve for the other unknown "A" using the substitution equation and the value of B we just found:
