It's B.) The student’s answer is not reasonable. Estimation: 170 + 90 = 260
25 as a decimal would just be .25
25 as a fraction would be 1/4
Hope this helps :)
Answer:
v = 0.416 m/s
Step-by-step explanation:
Give that,
Distance covered by a train, d = 50 m
Time taken, t = 120 s
We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :
![v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B50%5C%20m%7D%7B120%5C%20s%7D%5C%5C%5C%5Cv%3D0.416%5C%20m%2Fs)
So, the speed of a train is 0.416 m/s.
Answer:
A) Airplane A has a lesser median
Step-by-step explanation:
If you look at the photo you see both airplane A and airplane B and if you were to line them up
airplane A=3
airplane B=4 ½
so clearly airplane A would have a lesser median than airplane B
