Consider the formula d = rt, where d represents distance, r represents rate, and t represents time. how could the formula be rearranged to determine the number of hours it takes to reach kate's destination? a) t = dr b) t = rd c) t = rd d) t = dr in the given situation, how many hours will katie be traveling on the train? a) 5.1 hours b) 4.5 hours c) 4 hours d) 3.8 hours

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

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
