What is the arithmetic mean of the following
numbers?
10,6, 4, 4, 6, 4, 1

5

Step-by-step explanation:

When you add up the values you get 35, then you divide it by the number of numbers in the set, which is 7, so when you divide 35/7, you end up with 5.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
