The average speed : 3.07 m/s
<h3>Further explanation</h3>
Given
d1 = 2 km
t1 = 9 min
d2 = 1.5 km
t2 = 10 min
Required
The average speed
Solution
Average speed = total distance : total time
total distance :
= d1+d2
= 2+1.5
=3.5 km
total time :
= t1+t2
= 9 min + 10 min
= 19 min
Average speed :
= 3.5 km : 19 min
= 0.184 km/min
= 3.07 m/s

This question is incomplete, the complete part of the question is as follows:
This best demonstrates which type of an interaction between the plants?
A. cooperation
B. parasitism
C. commensalism
D. competition
The answer is D

Competition is the interaction between two organisms in which one or both organisms are harmed due to limited resources. Competition occurs when the organisms involved occupy the same niche or utilize the same limited resources.
In this question involving corn plants and milkweed plants. They are said to grow in the same area. Over several years, the milkweed plants have taken over the field and the corn plants no longer have space to grow. In this case, there is a limited space for growth, hence, the corn plant and milkweed COMPETE.

Answer:
Hydrogen bonding.
Explanation:
Ammonium lauryl sulfate is also known as ammonium dodecyl sulfate there are two parts in Ammonium lauryl sulfate one is nonpolar hydrocarbon and other part polar sulfate group.
Due to polarity of sulfate group its form hydrogen bond very easily.
It is mainly used as foaming agent the main reason of its use is very much soluble in water and making hydrogen bond with water.
