Some students are taking a math contest in which each student takes one of four tests. One third of the students take the first test, one fourth take the second test, one fifth take the third test, and 26 students take the fourth test. How many students
are taking the contest in total?

PLS GIVE EXPLANATION !!!

120

Step-by-step explanation:

Let x students are taking the contest in total.

According to the given information:

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

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
