Hm good question. Maybe you can measure the temperature in a place and measure another temperature in a other place and add it together.
Answer:
The correct answer is : C
Step-by-step explanation:
Answer: 4 seconds
Step-by-step explanation:
Given: The function
can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get

Put h'(t)=0

Also, 
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
The answer is realistic. I hope this helps ! :)
