The formula for Average speed = \frac{Total Distance}{Total Time}

The car travels 80 km in 1 hour.

Then the car travels 90 km in 2 hours.

And finally the car travels 76 km in 1 hour

So the total distance covered by the car = 80 + 90 + 76 = 246 km

The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.

So average speed = \frac{246}{4}= 61.5

The average speed of the car is 61.5 km / h

Leena walked 2/3 of a mile What is 2/3 written as a sum of unit fractions with the denominator of nine
aliya0001 [1]
Bear in mind that multiplying anything, and anything whatsoever by 1, has a product of the anything itself.

so, let's multiply 2/3 by 1 then and check about,

\bf \cfrac{same}{same}=1\qquad thus\cfrac{2}{3}\cdot 1\implies \cfrac{2}{3}\cdot \cfrac{3}{3}\implies \cfrac{6}{9}
\\\\\\
\textit{now, we can split that and write it as a sum}\implies \cfrac{1+5}{9}\implies \cfrac{1}{9}+\cfrac{5}{9}

Answer:

6 ft

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2

216 = 6s^2

Divide each side by 6

216/6 = 6s^2/6

36 = s^2

Take the square root of each side

sqrt(36) = sqrt(s^2)

6 =s

Each side is 6ft
