Two friends, Jim and Helen, ran a 112.km marathon 20 minutes later
and after running 950 meters, Helen sprained her ankle and had to
discontinue the roce. Jim stopped for 10 minutes to help her and then
continued to complete the race in 1 hour 45 minutes.
a.
How much farther did Jim run? (Give your answer in meters.)
b.
How long did Jim take to complete the race in minutes?!
C.
If the marathan started at 8:15 A. M., at what time did
Jim finish the race?

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

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
