In 1.8 hours, a sailboat sailed 81 kilometers east across the sea at a constant velocity. What was the sailboat’s velocity?
To find the velocity of the sailboat, we need to divide the distance it traveled by the time it took to travel that distance.
Velocity = Distance / Time
In this case, the distance traveled by the sailboat is 81 kilometers and the time taken is 1.8 hours.
Velocity = 81 kilometers / 1.8 hours
Velocity = 45 kilometers/hour
Therefore, the sailboat's velocity is 45 kilometers per hour.
