When designing an experiment, the first step is to a. draw conclusions c. recognize a problem b. form a hypothesis d. test a hypothesis

Recognize a problem

Explanation:

we cannot create a hypothesis or jump to conclusions about something that we have not yet defined so the first step in solving a problem is to recognize it and formulate it.

Once we have recognized the problem we can make a hypothesis and then test the hypothesis. Once we do tha, and depending on the results that we obtained, we can draw conclusions.

But fist step: Recognize the problem.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
