The formula R= - 0.075 + 3.85 can be used to predict the world record in the 1500 meter run, t years after 1930. Determine an inequality that identifies the years in which the world record will be less than 3.4 minutes.

The function

R(t)= - 0.075 + 3.85
does not have a variable t in the expression. Could you double check the formula?

To determine the years in which the world record will be less than 3.4 minutes, we can substitute 3.4 into the formula and solve for t.

The formula given is R = -0.075t + 3.85, where R represents the world record in the 1500 meter run and t represents the number of years after 1930.

Substituting R = 3.4 into the formula, we get:
3.4 = -0.075t + 3.85

To solve for t, we can isolate the variable by subtracting 3.85 from both sides of the equation:
3.4 - 3.85 = -0.075t

Simplifying,
-0.45 = -0.075t

Now, divide both sides of the equation by -0.075 to solve for t:
-0.45 / -0.075 = t

t = 6

Therefore, the world record will be less than 3.4 minutes t years after 1930, where t is greater than 6. Rounded to the nearest whole number, t is greater than 6.
