Answer:
0.6 km/hr
Step-by-step explanation:
Speed downstream: 13/5= 2.6 km/hr
Speed upstream: 7/5= 1.4 km/hr
Therefore, Velocity of current is: 1/2 (2.6-1.4) km/hr = 1/2(1.2) km/hr
This would depend on what you are asking for.
If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.
You get this by finding a common denominator. In this case, that can be 4.
Turn 1/2 in to 2/4.
Next, you add 11 and 13 to get 24.
Then, you’ll add 2/4 and 3/4. You will get 1 1/4
Add 24 and 1 1/4. You have your answer of 25 1/4
Just multiply w*l*h

Answer:
The answer to your question is: 35 yd²
Step-by-step explanation:
To solve this problem, just find the data, the formula, substitute the values in the formula and find the result.
Data
Square yards = ?
Length = 21 ft
Width = 15 ft
Formula
Area of a rectangle = length x width
Substitution
Area of a rectangle = 21 ft x 15 ft
Area of a rectangle = 315 ft²
Area of a rectangle = square yards of carpet
Finally, convert ft² to yd²
315 ft² = 35 yd²
Result
Square yards of carpet = 35 yt²
For the circumference, you actually multiply by 20 because of the formula πd = C [OR 2πr = C]. You meant to double the radius.
