Mary Jane made 140 cupcakes for the sixth grade classes at Oak School. She frosted 3/5 of the cupcakes with caramel icing and put sprinkles on 1/2 of those cupcakes. How many caramel cupcakes had sprinkles?

A)
38 cupcakes

B)
42 cupcakes

C)
44 cupcakes

D)
46 cupcakes

B). 42 cupcakes

Step-by-step explanation:

3/6= 0.6

1/2=  0.5

140*0.6=84

84*0.5=42

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

uhhh idk u yolo?
