Answer:
The lines will intersect 595 times.
Step-by-step explanation:
We can do it in 2 methods.
<u>1st method:-</u> Let us count the number of intersections by drawing lines one by one.
1st line - 0 points=0
2nd line- new 1 point=1
3rd line - old 1 point + new 2 points with two old lines = 1+2
4th line - old (1+2) points+ new 3 points= 1+2+3
5th line - old (1+2+3) points + new 4 points=1+2+3+4
Like that from 35th line-1+2+3+4......34 = 
<u>2nd method:-</u>
We have to choose 2 lines from 35 lines.
We can do it in 
ways = 595 points
0.06 is the correct answer bud
We have two unknowns and two equations so we can solve this question.
The two unknowns are C (speed of current) and B (speed of boat)
Our boat traveled 20 miles in 55 hours going upstream which means it traveled .36 miles in 1 hour; in other words .36mph . Our boat traveled 50 miles in 55 hours going downstream; in other words .909mph .
We can assume that because the boat managed to cover distance in the direction it was headed upstream it must have been going faster than the current so it moved at the speed of the boat minus the speed of the current and when it was going downstream it moved at the speed of the boat plus the speed of the current.
This gives us;
.36mph = B - C
.909mph= B + C
We solve for this system of equations and it simplifies to 1.27mph=2B
and B= .636mph
Plug this into one of the equations and we get that C= .2727mph
This means that the boat moved at .363mph and the current moved at .2727mph.
