The cart’s speed in miles per hour is 14.2 miles per hour .

Option (B) is correct .

Step-by-step explanation:

As given

Rob measures his go-cart’s speed to be 250 inches per second.

As

Now convert 250 inches per second into miles per hour .

250 inches per second = 14.2(Approx) miles per hour.

Therefore the cart’s speed in miles per hour is 14.2 miles per hour .

Option (B) is correct .

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
