Answer:
30 minutes earlier
Step-by-step explanation:
Since the friend lives 300 miles away, they each have to travel 150 miles which is half of that distance. If the friend travels at 50 miles per hour, they will take 3 hours to reach the destination. If you traveled 60 miles per hour, then you would take 2.5 hours, therefore making it there before him by half an hour.
150/50 = 3
150/60 = 2.5
hope this helps :^)
The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9 
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30
Thus the area of the square increasing at 30
