Average speed
Average speed between the checkpoints
distance between the checkpoints
divided by
time between the checkpoints.
Distance between the checkpoints =
(mileage at B) minus (mileage at A)
=(208)-(120) = 88 miles .
Time between the checkpoints =
time at - time at A
=(3:00 PM) - (1:00 PM) = 2 hours .
Average speed between the checkpoints =
(88 miles) / (2 hours)
=44 miles per hour .
10101₂ = 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰
10101₂ = 16 + 0 + 4 + 0 + 1
10101₂ = 21
The x-intercept is -2, since the line intersects with the x-axis at (-2, 0).
The y-intercept is 1, since the line intersects with the x-axis at (0, 1).

Answer:
1715 metros
Step-by-step explanation:
Lo que debemos hacer es calcular la distancia del primer y del segundo eco.
Debemos conocer la velocidad del sonido que en términos generales es 343 m/s, por lo tanto, la distancia sería igual a:
v = d/t => d = v*t
d1 = 343*2 = 686 metros
d2 = 343*3 = 1029 metros
La separación sería la suma de ambas distancias así:
686 + 1029 = 1715
1715 metros sería la distancia de separación entre ambas montañas.
Answer:
The coordinates of the point S = (12, -22)
Step-by-step explanation:
The coordinate points of T = (0,6)
Mid point of ST = (6,-8)
Let the coordinates of S = (a,b)
Now, BY MID POINT FORMULA:
If (x, y) and (z, w) are the line point joining line segment and (p,q) is the coordinate of mid point. Then
So, here similarly, 
⇒ 
⇒ a =2 x 6 = 12, b = 2 (-8) -6 = -22
⇒(a,b) = (12, -22)
Hence, the coordinates of the point S = (12, -22)
