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

C would be the correct answer because you want to get H alone. since everything is connected to it, divide by everything except H because that is what you are finding. that leave h= whatever is left as v divided by the stuff connected to H. (the denominator and v as the numerator). the answer that matches that correct work is c.
