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.
Solve for T
(Round to the nearest whole number)
R(t)= - 0.075 + 3.85
does not have a variable t in the expression. Could you double check the formula?
