Given the following expressions: a. 53 • 5-4 b. c. • d. part 1: use operations of exponents to simplify each expression (a-d). include your work in your final answer. part 2: for each simplified expression (a-d), tell whether or not the expression has a value between 0 and 1.

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

-14 is the answer

hope this : ))
