Velocity is 30 m/s
62.22 mph.
DISTANCE + VELOCITY x TIME So if you travel 90 miles in two hours, 90 = velocity x 2 velocity = 45 miles per hour After 7 hours DISTANCE = 45 x 7 = 315 miles
The velocity is 83 miles per hour in some, unspecified, direction. Remember, velocity is a vector, so the direction needs to be specified.
It's 70 mph west
Speed gives you information about how fast something is going (it is scalar), on the other hand velocity is a vector and gives you directional information also, for example if you drive 50 kmph for a few hours from point A to a point B, and return to point A, your velocity is zero since the vector sums are zero
Time = Distance/Velocity = 2000/55 = 36.3636.. hours = 36 hours 21.8181.. minutes
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. : Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
