The moon is approximately 221,000 miles from the Earth. Drag the tiles to represent 221,000 in scientific notation.

The scientific notation is .

Solution:

Let us first define the scientific notation.

Scientific notation is used to write large numbers in a small manner.

Rule to write the Scientific notation:

For example:

500 can be written as 5 × 10².

6500 can be written as 6.5 × 10³.

Given data:

Distance from Earth to Moon = 221,000 miles

To write this in a scientific notation.

221,000 =

Hence the scientific notation is .

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
