We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc.  For this type of problem you use the "n choose k" formula...

n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..

In this case:

Answer: 28.35\ minutes

Step-by-step explanation:

Let be "x" the time in minutes a 150-pound person must walk at  4 mph to use at least 190 calories.

 The amount of calories that a 150-pound person uses  in 1 minute when walking at a speed of 4 mph is:

Calories\ per\ minute=6.7

Therefore, knowing this, we can write the following proportion:

\frac{1}{6.7}=\frac{x}{190}

Finally, we must solve for "x" in order to find its value.

Multiplying both sides of the equation by 190, we get this result:

(190)(\frac{1}{6.7})=(\frac{x}{190})(190)\\\\x=28.35
