Four hundred draws will be made at random with replacement from the box [1,3,5,7] a) Find the chance that the sum of the draws will be more than 1500.
b) Find the chance that there will be fewer than ninety 3s.

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

x=0
