Average Speed= Total Distance/Total Time

=(100+30)/(1+2)

=(130miles)/(3hours)

=43.333mph

average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour

10 miles per hour speed is not a vector quantity, therefore direction does not matter. 16 miles/ 2 hours=8 mph 24 miles/ 2 hours=12 mph (8+12)/2=10 mph average

25 miles.

Divide the distance by the time to get the speed. The direction, of course, is north-east.

Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.

Rough distance in miles from Munich to Karlsruhe is 158 miles or 254 Kilometer or 137 nautical miles.Driving at an average of 70mph, it would take 2.25 hours to reach Karlsruhe from Munich.Your travel direction from Munich to Karlsruhe is NW (-67 degrees from North).Safe Travels!--DrJay

NC to NY takes an average of 9 hours by car.It takes about 3 hours by plane.

Velocity is speed and direction. The velocity would be zero because the 50 miles N cancel the 50 miles S. The speed is 100 mi/5 h = 20 mph.
