Aclass is made up of 10 boys and 4 girls. half of the girls wear glasses. a student is selected at random from the class. what is the probability that the student is a girl with class

2/14 or 1/7

Step-by-step explanation:

Add the student together to get the number of students

10+4

14

Divide the girls by half

4/2

2

2/14 is your answer reduced is 1/7

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
