Let us assume as at when they meet, the time elapsed is x hours.
Fred 3 mi/h
John 2 mi/h
Distance = speed * time
Fred = 3x
John = 2x
Houses are 4miles apart.
So: 3x + 2x = 4 5x = 4
x = 4/5 hour = 0.8 hour or 0.8*60 = 48 minutes
Time elapsed is 0.8 hour or 48 minutes.
I believe the answer is C.
<span>6m + 1 = 23
Reorder the terms:
1 + 6m = 23
Solving
1 + 6m = 23
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 6m = 23 + -1
Combine like terms: 1 + -1 = 0
0 + 6m = 23 + -1
6m = 23 + -1
Combine like terms: 23 + -1 = 22
6m = 22
Divide each side by '6'.
m = 3.666666667
Simplifying
m = 3.666666667 i think</span>
