Answer:

Step-by-step explanation:
The algebraic expression states that
"The class we divided into four equal groups."
We have our expression right at the word of "divided", therefore the answer would be a division problem.
w over 4 fits this because it fits the expression, w - class and 4 - amount of groups.
4 + w - Would be the class added four groups
4w - The class multiplies four more groups
4 - w - Four groups was taken from the class

226.19 x 3/2 =
226.19 x 1.5 =
339.285
339.285 is your answer.
Answer:
Step-by-step explanation:
- Speed in one direction = 40 km/h
- Speed on return = x
- Average speed = 60 km/h
Let the distance be d
<u>Average speed </u>
- 2d/(d/40 + d/x) = 60
- d/40 + d/x = 2d/60
- 1/40 + 1/x = 1/30
- 1/x = 1/30 - 1/40
- 1/x = (4-3)/120
- 1/x = 1/120
- x = 120 km/h
