In a survey, some children were asked to choose whether they like to stay up late or get up early. 35% of the students said they prefer to get up early. 28 students prefer getting up early. How many students in total were surveyed?
students

80 Students

Step-by-step explanation:

So I set up my problem like this(This is a way to figure a certain amount of a percent or vice versa):

35            28

=

100         x

First, you do 100 x 28= 2800

Second, do 2800 divided by 35= 80

The number in students surveyed is 80.

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
