Recall your d = rt, distance = rate * time.
now, if the boat has a speed of say "b", and the current has a speed of say "c", when the boat is going upstream, is not really going "b" fast, is going " b - c " fast, because the current is eroding speed from it, going upwards.
And when the boat is going downstream, is not going "b" fast either, because the current is now adding to speed to it, so is really going " b + c " fast.
The time it took one way, is the same time it took back, 4 hours each way.
thus
what's the speed of the boat? well, 5 + c = b.

Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:
Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:
Simplify:
Square:
Add:
And that's our answer :)
<h3><u>Answer:</u></h3>
- 400 is the number.
<em>There can be many ways to find the number.</em><em> I have found the number with the help of fractions and multiplication. </em><em>Below is the solution to your problem.</em>
- 80 = 20/100
- => 5 x 80 = 20 x 5/100
- => 400
<em>Hence, 80 is 20% of 400. </em><em>I hope my method helped you.</em>
