LaTanya leaves her house at 12:30pm and bikes at 12 mi/h to marta’s House she stays at marta’s House for 90mij both girls walk b
babymother [125]

Answer:

2.9 mi

Step-by-step explanation:

The time difference t between 12.30pm and 3.30pm is 3h.

Let the distance to Marat's house be s.

The equation to calculate velocity v is given by:

v = distance / time.

Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:

3 = s/12 + 1.5 + s/2.3

Solve this equation for s:

(1/12 + 10/23)* s = 1.5

s = 2.9

How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?
ElenaW [278]

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

<u>Work done ( in joule, J) = 21 J (in joule)</u>
