What is the formula to calculate the total toll cost for multiple vehicles?

Back

Total Toll Cost = (Number of Cars * Cost per Car) + (Number of Buses * Cost per Bus)

Front

If the toll cost for one car is $5.00 and for one bus is $7.50, what is the total cost for 3 cars and 1 bus?

Back

Total Cost = (3 * 5.00) + (1 * 7.50) = 15.00 + 7.50 = 22.50

Front

What is velocity?

Back

Velocity is the rate of change of position with respect to time, and it includes both speed and direction.

Front

How do you calculate velocity?

Back

Velocity = Displacement / Time

Front

If an object travels 80 meters in 2 seconds, what is its velocity?

Back

Velocity = 80 meters / 2 seconds = 40 meters/second

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the unit of velocity in the metric system?

Back

The unit of velocity is meters per second (m/s).

Front

If a car accelerates from rest to a speed of 60 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time = (60 m/s - 0 m/s) / 5 s = 12 m/s²

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is the significance of a negative velocity?

Back

A negative velocity indicates that an object is moving in the opposite direction to the defined positive direction.
