Final answer:
The distance covered after t seconds at a rate of 1.5 meters per second is calculated using the formula d = 1.5 × t, where d is the distance in meters.
Step-by-step explanation:
The question relates to velocity and distance covered by an object moving at a constant rate. If a race begins at a rate of 1.5 meters per second, to find the distance d covered after t seconds, you would use the formula d = rate × time. Thus, the distance covered d after t seconds is d = 1.5 × t meters. This is a representation of the basic concept of distance calculation from speed and time in kinematics, which is a part of physics.
