Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
King can do the job in 13.33 Hours

King could mow (1 / 13.33) of the lawn in one hour.

Leviafan [203]

Answer:

\displaystyle a=\frac{d}{.5*t^2}

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

d=.5*a*t^2

It's required to solve it for a.

Swap sides to have the letter on the left side:

.5*a*t^2=d

Divide by .5*t^2:

\mathbf{\displaystyle a=\frac{d}{.5*t^2}}
