Can any of you with both questions and

Fun. It took Joelle 1/4 hour to get there.  It took Andrea 1/2 hour and Kellan 3/4 hours.

Their distances are simply rate times time,

j = 35(1/4) = 35/4 = 8.75 miles

a = 3(1/2) = 1.5 miles

k = 14(3/4) = 21/2 = 10.5 miles

10.5 miles

Next part.  It took Kellan 12/15=4/5 hour to bike to Andrea.  

Let's assume it's the same restaurant.  They had to walk 1.5 miles, which they did at 2.5 mph, 1.5/2.5=3/5 hours.

So Keelan traveled for 4/5+3/5=7/5 hours, which is 1 hour, 24 minutes.

They got there 5 minutes early, 8:55, so Keelan left at 7:31 am

7:31

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
