Total distance = 200 miles
Time needed for the first 100 miles
= 100 ÷ 40 = 2.5 hours
Time needed for the second 100 miles
= 100 ÷ 50 = 2 hours
Total time = 2.5 + 2 = 4.5 hours
Average speed = 200 ÷ 4.5 hours = 44.4 miles per hour

Answer:
7y(3x+2)
you take out the 7y from both sides
The area of the square is 14*14 = 168 ft^2.
The area of the circle is πr^2. The radius is diameter/2 = 7. The area of the circle is 3.14*(7)^2 = 3.14*49 = 153.86 ft^2.
The area of the shaded part is the area of the square minus the area of the circle = 168 - 153.86 = 14.14 ft^2.
