The 2020 senior class from a high school raised funds for an end of the year prom at Club Dance. It costs $4,000 to rent out Club Dance plus $20 per student for food and drinks. Write an equation for the number of students could attend if the senior class raised 11,000 dollars.

4000 + 20x = 11,000

Step-by-step explanation:

4000 + 20x = 11,000

20x = 7,000 (subtract 4,000 from 11,000)

7,000/2 = 3500

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
