Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 30 miles at a speed of 6 mph, while Bob's motorboat traveled 70 miles at a speed of 14 mph. For how long were Niles and Bob traveling?

5 hours

Step-by-step explanation:

As both of them sailed for the same time, take the speed and distance of either of them to find the time they traveled:

Niles' Time = Distance / speed

= 30 / 6

= 5 hours

Bob's time = 70 / 14

= 5 hours  

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

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
