Miss Solan is buying doughnuts and coffee for her classes. The total came out to $32.12. If the coffee costs $5.96 and each doughnut is $1.09 ,how many doughnuts did she buy?​

24

Step-by-step explanation:

First, start off by subtracting the cost of the coffee ($5.96) from the total cost of $32.12. This would give you $26.16. From here, if you multiply 24 by the cost of each doughnut  ($1.09) you would get $26.16 which is the total amount of money that was spent on doughnuts. Miss Solan bought 24 doughnuts.

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
