Answer:
See explanation
Explanation:
Recall that;
Speed = Distance/time
Distance = Speed * time
Speed = 200 km/h
Time = 4 hours
Distance = 200 km/h * 4 hours = 800 kilometres
Displacement has to do with distance covered in a specified direction, in this case, the direction is towards Zambales.
Hence, the displacement is 800 kilometres towards Zambales.
Answer:
0.0258 mol <em>Answer</em><em> </em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>
Let's make ;
A = ounces solution A
B = ounces solution B
total number of ounces:
A + B = 120
concentration:
0.65A + 0.80B = 0.7(120)
Substitute A for 120 - B in the second equation to combine them.
0.65(120 - B) + 0.80B = 84
78 - 0.65B + 0.80B = 84
0.15B = 84 - 78
0.15B = 6
B = 6/0.15
B = 40 ounces
Then... A = 120 - 40
A = 60 ounces
