Kellen’s boat travels 6 mph. Find the rate of the river current if she can travel 2 mi upstream in the same amount of time she can go 4 mi downstream. Let x = the rate of the current. The rate of the river current is ___ (mi, mph, or hr?)

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
