d = rt
Solve for her rate
21 = 5r
r = 21/5
r = 4.2

d = 4.2*2
d = 8.4
Answer:
See explanation and proof below.
Step-by-step explanation:
For this case we want to proof this identity:
And we need to us the double angle formula given by:
If we use a substitution for example we see that the double angle formila is given by:
And we got:
And if we apply sqaure root on both sides we got:
And that complete the proof
