Hi, can you help me with this please? You can jog at a speed of 7 miles per hour and run at a speed of 12 miles per hour. If you traveled 8 miles in 50 minutes, find the amount of time you jogged as well as the amount of time you ran.

He jogged for 24 minutes and ran for 26 minutes

Step-by-step explanation:

Mathematically,

distance = speed * time

Let the amount of time jogged be x and the amount of time ran be y hours

50 minutes to hours = 50/60 = 5/6

so x + y = 5/6

Total distance jogged is 7x and total distance ran is 12y

7x + 12y = 8

So we have two equations;

x + y = 5/6

7x + 12y = 8

From i, x = 5/6-y

So;

7(5/6 - y) + 12y = 8

35/6 - 7y + 12y = 8

Multiply through by 6

35 + 30y = 48

30y = 13

y = 13/30

13/30 in minutes is 13/30 * 60 = 26 minutes

So the amount of time jogged is 50-26 = 24 minutes

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
