Answer:
90 mph
Step-by-step explanation:
Average speed is given by
Average speed=(initial+final speed)/2
Given average speed of 60 mph then considering initial speed of 30 mph. Let x be the final speed hence
60=(30+x)/2
120=30+x
X=120-30=90 mph
Therefore, the return trip speed is 90 mph
Answer:
This is an odd question, I keep getting 0. But your answer is probably 2.
tan(2x) is a double angle and can be simplified to : 2tan(x)
I tried solving for when it equals 0 and my answer is still the same. Very odd. I would select 2.
Edit: Original poster confirmed it was 2
