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:

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