There are 5280 feet in a mile. So divide 607,200 feet by 5280 to get 115. The go-kart's speed is 115 miles per hour.
Step-by-step explanation:

(3.8×10^8)×(6.9×10^5)= 2.622e^14
Okay so first of all you are going to cross multiply, which is simply multiplying diagonally across so (6x×5 and 25×3) then you just answer each part and set them equal to each other so (30x=75). Then you just divide 30 on each side which ends up being (x=2.5)
Answer:

Step-by-step explanation:
Find the area of the square - area of 4 sectors
We'll use the formula to find one sector area

where r is the radius of one sector and x is the angle in radians
Since each angle is in a square, the angle of the sectors is 90 degrees.
Convert degrees to radians

The radius of one sector is given by 70mm/2=35mm
One sector area:

Area of all 4 sectors:

Area of the square:

Hence, Area of square - 4 Sectors:
