Answer:
I think you are looking for the velocity, so the answer is 38.5 m/s
Explanation:
Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.
Explanation:
1 mile = 1609m
Distance=260 miles= 418340 m
Speed= 40 m/s
Time = distance/speed
= 418340/40
=10458.5 seconds
= 2.9 hours
A major obstacle to developing a good human relations skill is that : few person have a common interest a communication between two people will be a lot easier if they have common interest because a person tend to like other person that are similar to him (whether it's race, background , or common interest).
A compound. For example, hydrogen and oxygen atoms form water.
Frequency is not a length of time. It's exactly the opposite.
Frequency tells you how often something happens. In fact,
the unit 'Hz' means 'per second'.
Frequency of 2 Hz means "It happens at 2 per second."
The time it takes for the thing to happen once is exactly the
'reciprocal' of the frequency ... ' 1 ' divided by the frequency.
If the frequency is 2 Hz, then the thing happens every 1/2 second.
If the frequency is 74 Hz, then it happens every 1/74 of a second.
If the frequency is 1 KiloHz, then it happens every 1/1000 second.
