The sum of three numbers is -39.22. One of the numbers is 22.8. The other two numbers are equal to each other. What is the value of the other two numbers?

The value of the other two numbers is 31.01

Step-by-step explanation:

Let the two numbers equal to each other be x

One of the numbers is 22.8

The sum of three numbers is -39.22.

So, x+x+22.8=-39.22

2x+22.8=-39.22

2x=-39.22-22.8

2x=-62.02

x=-31.01

Hence the value of the other two numbers is 31.01

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
