<span>So we need to find the average speed of the bus that travels 20 km in 30 minutes. Average speed is defined as: Average speed=distance travelled/time taken or: v=s/t. We know s=20 km and t=30 minutes=0.5h. So after we input our numbers in the equation, we get: v=20km/0.5h=40km/h. So the correct answer is C) 40km/h.</span>
Answer:
h = 8
Step-by-step explanation:
Area of rectangle: base * height
So, by substituting the values given, we can write this equation:
Note: 1/4 = 0.25, so 3 1/4 = 3.25
A = b * h
26 = 3.25 * h
Divide both sides by 3.25.
h = 8
I hope this helps! Feel free to ask any questions!
Step-by-step explanation:
Assume length of side 2 = L
Area of parallelogram is Height x L
So, 72 = 8 x L
L = 9
