Answer:
you: 25h + 100
friend: 20h + 120
same amount of pages: 4 hours
Step-by-step explanation:
Every hour you read 25 pages. I used h to represent hour. It doesnt really matter. That starts your equation at 25h. You already read 100 pages, so we simply add 100 and thats your equation. We use the same thinking for the friend's equation.
To find how many hours it will take for them to read the same amount, we write the equations as an equality. Because we need them to be the same, see?
Work through the equation to get your h on one side and the numbers on the other. We come up with 4.
8 / 200 = 4 / 100 = 0.04 ;
Answer: Nothing
Step-by-step explanation:
If you multiply the numerator and denominator of a fraction by any number(apart from 0), it doesn't change.

Recall your d = rt. distance = rate * time.
let's say the speed of the current is "c".
keeping in mind that, when the boat is going against the current, the boat is not really going at 2kmh, but instead at " 20 - c ", because the current is subtracting speed from it.
Likewise when is going with the current, is going at a speed of " 20 + c ".
if the boat took say "t" hours on the way over, on the way back it took the slack from the whole 8 hours and "t", namely it took " 8 - t " hours.
