Understanding Velocity-Time Graphs and Acceleration

What is the main task described in the video involving the party boat?

• To calculate the distance traveled by the boat.

• To determine the acceleration between 8 and 12 seconds.

• To analyze the fuel efficiency of the boat.

• To find the maximum speed of the boat.

How is the gradient of the velocity-time graph used in the video?

• To find the total distance traveled.

• To determine the boat's direction.

• To calculate the acceleration.

• To measure the time taken for the journey.

What is the purpose of drawing a triangle on the velocity-time graph?

• To help calculate the gradient.

• To visualize the change in velocity.

• To mark the start and end points of the journey.
