Answer:
The Average Speed of the Ball is 3.925 m/s
Step-by-step explanation:
Add All The Numbers Together
0.2+0.5+5+10
Divide By How Many Measurements There Are
And There Are 4 Measurements
15.7/4 = 3.925

Step-by-step explanation:
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
Let us first write down the given equation.
80 = 3y + 2y + 4 + 1
80 = 5y + 5
80 - 5 = 5y
75 = 5y
Just reversing both sides we get
5y = 75
Now dividing both sides by 5 we get
y = 15
So the value of y is 15.
I hope the procedure for solving the problem is clear to
you. In future you can solve such problems with ease following the procedure
described.
