Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
I think it’s D distributive property
Hi
-7 -6 -5 -4 -3 - 2 -1 0 1 2 3 4 5 6 7
The distances d₁ = -7 to 0 and d₂ = 0 to 7 are the same
<span>Answer: b) 7</span>
Answer: B. 240
Step-by-step explanation:
Let x be the number of pages Rafael read,
According to the question,
Number of pages Denise will read = 
And, the number of pages Philippe will read = 
Since, the total umber of pages = 540






Hence, the number of pages Rafael read = 240 pages.
⇒ Option B is correct.
Since we are finding total distance, we can just add both together.
5 + 2 = 7ft total traveled
Best of Luck!
