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.

What you gotta take from this problem:

What Joe got during break = 2t+2

What his sister gave him = 3t

What he has total = 10 tadpoles.


Now to assemble this equation:

2t+2+3t=10

Now combine like terms to get 5t+2=10

Subtract 2 on each side of the equation to get 5t=8

Now you would divide 5 on each side and get t=1.6 , however since you can't have a .6 of a tadpole, you would have to round it up to 2.
