The speed of a model car as it slows down is given by v = 20 - 4t, where v is the speed in meters per second (m/s) and t is the time in seconds (s) during which the car has slowed. find the speed of the car 1.5 s after it has begun to slow.

The speed of a model car as it slows down is given by v = 20 - 4t, where v is the speed in meters per second (m/s) and t is the time in seconds (s) during which the car has slowed. Find the speed of the car 1.5 s after it has begun to slow.

t = 1.5

v = 20 - 4t = 20 - 4x1.5 = 20 - 6 = 14 m/s

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
