Answer:
It would take about 2 hours or 120 minutes
Rx - sx + y = b
WHEN SOLVING FOR X :
rx - sx + y = b
We must get x onto it's own side, so subtract y from both side.s
rx - sx = b - y
Then, factor out x.
x(r - s) = b - y
Then, divide both sides by (r - s).
x(r - s) ÷ (r - s) = b - y ÷ (r - s)
Simplify.
x = b - y / r - s →
![x = \frac{b-y}{r-s}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7Bb-y%7D%7Br-s%7D%20)
WHEN SOLVING FOR Y :
rx - sx + y = b
We need to isolate y, so get rid of everything BUT y on the left side.
Subtract rx from both sides.
-sx + y = b - rx
Then, add sx to both sides.
y = b - rx + sx

Answer:
2 Hours
Step-by-step explanation:
4/7 of an hour = 34.3 minutes.
34.3 minutes per 2/7
4/7 = 68.6 OR 1 hour 8 minutes.
6/7 = 102.9 OR 1 hour 42 minutes.
Then add half of 34.3 (17.15)
7/7 = 120.05. = 2 hours 0.5 seconds.
It already is a decimal unless you mean a repeating decimal, it would be .26 with a line over the number.
