The upstream speed is 4 km/hour and the down stream speed is 6 km/hour
<h3>Calculating Speed </h3>
From the question, we are to calculate the speed of each stream
From the given information,
"<em>Rahul rows 16 km upstream and 24 km down stream taking 4 hours each</em>"
For the Upstream,
Distance = 16 km
Time = 4 hours
Using the formula,
Speed = Distance/ Time
Speed = 16 km / 4 hours
Speed = 4 km/hour
For the Down stream,
Distance = 24 km
Time = 4 hours
Thus,
Speed = 24 km / 4 hours
Speed = 6 km/hour
Hence, the upstream speed is 4 km/hour and the down stream speed is 6 km/hour

Answer:
2
Step-by-step explanation:
Because 8x4 is 32 and 32x2 is 64 so it’s 2
Answer:
b =± 5 sqrt(3)
Step-by-step explanation:
f(b) = b^2 – 75
To find the roots set the equation equal to zero
b^2 -75 =0
Add 75 to each side
b^2 – 75+75 = 0+57
b^2 = 75
Take the square root of each side
sqrt(b^2) = ±sqrt(75)
b = ±sqrt(3*25)
We know that sqrt(ac) = sqrt(a) sqrt(c)
b = ±sqrt(3)*sqrt(25)
b =± 5 sqrt(3)
The answer is 1/5

Answer:
19 dollars
Step-by-step explanation:
What you have to do is find a way to make sure each book is the same price and it lowers to 16. First rule out 1-10. It wouldn't be possible. Next, try and start with the even numbers (16, 18, 20, and so on). It can't be twenty because 20 x 8 equals 160 and you're left with 16 dollars, not 8. so it's either 14, 15, 16, 17, 18, or 19. I calculated with my calcuator that it's not any of the answers but 19. So try it out!
