Find the velocity of a runner that complete 400 meters in 56 seconds

Answers

Answer:

Step-by-step explanation:

As long as the runner does not change direction, the velocity would be

Formula

d = r*t

r = d/t

Solution

r = 400 m  / 56 s

r = 7.14 m/s

Answer:

The correct answer , velocity = 7.14 m/s

Step-by-step explanation:

Formula:

Velocity = Distance/Time

The common units are km/hr and m/s

It is given that,  a runner that complete 400 meters in 56 seconds

From the given information we get,

Distance = 400 m and time = 56 s

To find the velocity

Velocity = Distance/Time = 400/56 = 7.14 m/s

Therefore the correct answer , velocity = 7.14 m/s

I hope this helped :)
20/100 simplifies down to 1 / 5.

You can divide both numerator and denominator by 20 because its the LCD of both numbers if you needed to show proof. :)

Can someone help me with 9, 10, & 11

Answers

Answer:

1)For, m =  3/4 ,  (0,4)  , 4y - 16 - 3x = 0  is the equation of line.

2)For, m =  4 ,  (-2,-5)  , y -  4x - 4  = 0  is the equation of line.

3)For, m =  -1/3 ,  (4,-1)  , x + 3y -1  = 0  is the equation of line.

Step-by-step explanation:

If m is the slope and (x0,y0) is the point on any given equation, then

by POINT SLOPE FORMULA:

The line equation is given as (y - y0) = m (x -x0)

Now , here:

1) m =  3/4 , (x0, y0) = (0.4)

So,, the equation of line is (y-4) = (3)/(4) (x-0)\nor, 4(y-4)  =  3x

on simplification,  4y - 16 - 3x = 0  is the equation of line.

2) m =  4 , (x0, y0) = (-2.-5)

So,, the equation of line is (y-(-5)) = 4 * (x-(-2))\nor, (y+4)  =  4(x+2)

on simplification, y -  4x - 4  = 0  is the equation of line.

3) m =  -1/3 , (x0, y0) = (4, -1)

So,, the equation of line is (y-(-1)) = (-1)/(3) (x-4)\nor, 3(y+1)  =  -(x-4)

on simplification,   x + 3y -1  = 0  is the equation of line.
