<span>1 hour 36 minutes = 1 36/60 = 1 3/5 = 1.6 hours
Speed of car leaving wallace be x mph
Speed of car leaving vernonville will be ( x+10) mph
1.6 ( x + x+10) = 192
2x + 10 = 120
2x = 110
x = 55
ANSWER Wallace car = 55 mph Vernonville = 65mph
Therefore, </span><span>the average speeds of both cars are 55 mph for the Wallace car and 65 mph for the Vernonville.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>
Not sure this is a physics question (probably biology).
Anyway, the correct answer is A):
"Plasticity helps us to adapt to our environment. It also generally decreases with age".
Plasticity is the ability to adapt to the environment. Since this ability is linked with brain functions, and brain functions worsen with age, then plasticity decreases with age.

What you want to test and your hypothesis does.
For example, say you came up with a hypothesis that 'The higher the temperature, the higher the reaction rate will be'.
Your independent variable (the one you change) will be temperature. The dependent variable (the one that changes because of the independent) will be the reaction rate (e.g. bubbles produced).
