The price of the single cone at the ice cream store went from $2 to $3. What was the percent increase?

50%

Step-by-step explanation:as you know the first price was 2 which will be equal to 100 as it is the original price so

2=100%

3=X cross multiply 3×100÷2=150 then minus 150 from 100 so answer is equal to 50%

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

you have to put the graph on here with the question
