Acar travels 300 miles on level terrain in the same amount of time it travels 175 miles on mountainous terrain. if the rate of the car is 25 miles per hour less in the mountains than on level ground, find its rate in the mountains.

Answer

x = 50 mph (level rate)

x-30 = 20 mph (mountain rate)

Explain:

time = time

160/(x-30) = 400/x

160x = 400(x-30)

160x = 400x - 12000

-240x = -12000

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

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
