A person is initially driving a car east down a straight road. the magnitude of the instantaneous acceleration is decreasing with time, but the direction of the acceleration is always to the east. the speed of the car is

By definition, acceleration is the change in velocity per change of time. As time passes by, the time increases in value. So, when the acceleration is decreasing while the time is increasing, then that means that the change of velocity is also decreasing with time. So, optimally, the initial velocity and the velocity at any time are very relatively close to each other,
