Question

If a boat travels 20 km in 3 h due north, what is the boat's average velocity?

a) 6.67 km/h
b) 10 km/h
c) 15 km/h
d) 20 km/h

Answer 1

The average velocity of the boat is calculated as the displacement divided by the time taken, which is 6.67 km/h due north.

Step-by-step explanation:

If a boat travels 20 km due north in a time span of 3 hours, we calculate the boat's average velocity by dividing the total displacement by the time taken. To find the average velocity, we use the formula:

Velocity = Displacement / Time

Substituting the given values:

Velocity = 20 km / 3 h = 6.67 km/h

Therefore, the boat's average velocity is 6.67 km/h due north, which corresponds to option a).
