In 1960, the world record for the men's mile was 3.91 minutes. In 1980, the record time was 3.81 minutes. a. Write a linear model that represents the world record (in minutes) for the men's mile as a function of the number of years, $t$ , since 1960.

$y=$

b. Use the model to estimate the record time in 2000 and predict the record time in 2020.

2000:
minutes

2020:
minutes

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

the answer is d on edge

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
