In how many ways can we put five identical fruits into three bowls? Note that the bowls may be empty. The answer is not 243.

6 ways

Step-by-step explanation:

The way to solve for this is to use the formula

Combination C (n-1, r-1)

= n = 5 identical fruits

r = 3 bowls

So, we have: 5 - 1 = 4

3 - 1 = 2

= 4!/2! (4-2)!

= 4 × 3 × 2 × 1/(2 × 1 )(2 × 1)

= 6 ways

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
