Stop and look. always treat a railroad crossing with no lights or gates like a stop sign.
Answer:
Explanation:
Formula
d = r * t
r = rate
t = time
d = distance
Givens
d = ?
r = 121 km/hr
t = 3 hours 20 minutes. The units have to be the same. If one part of the time is in hours, then both should be in hours..
20 / 60 = 1/3 of an hour
t = 3 1/3 hours = 10/3 hours.
Solution
d = 121 km / hour * 10/3 hours
d = 1210 /3
d = 403.33 km
The distance travelled is 403.33 km
The output winding has 1/20 as many turns as the input winding has.
So the output voltage is 1/20 of the input voltage.
That's how transformers work.
Complicated, huh !
(1/20) of 240 volts = <em>12 volts</em>
Yes. I think it is. If you are wasting your time staring at a wall, but you are enjoying it and still have work to do, you are wasting your time. Sometimes the point of wasting time is to, well waste time, but that doesn’t change the fact that you are wasting your time.
