Answer:
Speed of boat in still water is 26km/hr
Step-by-step explanation:
Let the speed of boat in still water be x and speed of stream by y.
Speed at which it went upstream would be (x-y) and the speed at which it went downstream would be (x+y). According to question x+y=24 and x-y=28. x=26 and y=-2.
Answer:

The name of the ray shown would be: C. ray AG.
<h3>What is a Ray?</h3>
A ray can be defined as a part of a line which has a fixed starting point that is called an endpoint and extends to infinity towards the opposite direction of the fixed point, called the endpoint.
<h3>How to name a Ray?</h3>
The first letter to use when naming a ray is the letter of the endpoint, which is the starting point of the ray, then use another letter that the ray passes through to infinity. There would be only one arrow head facing the right, drawn on top of the letters used in naming the ray.
The image shows an endpoint of A, which marks the starting point. The line extends from G to infinity as well.
Therefore, the name of the ray shown would be: C. ray AG.
