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
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
on simplification, 4y - 16 - 3x = 0 is the equation of line.
2) m = 4 , (x0, y0) = (-2.-5)
So,, the equation of line is
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
on simplification, x + 3y -1 = 0 is the equation of line.
The answer would be 0.19
