Final answer:
Sheldon the turtle will take approximately 121.21 seconds to cover 4.0 meters at his constant velocity of 3.3 cm/s.
Step-by-step explanation:
To determine how long Sheldon the turtle will take to cover 4.0 meters at a constant velocity of 3.3 cm/s, we need to convert the distance from meters to centimeters since the velocity is given in cm/s. First, convert 4.0 meters to centimeters: 4.0 meters = 400 cm. Next, use the formula for time which is time = distance / velocity. Calculate Sheldon's time to cover 400 cm at 3.3 cm/s: time = 400 cm / 3.3 cm/s = approximately 121.21 seconds.
