GS BEST PRACTICE MOTION

How far did a car, with an average speed of 60 kph, travel in 14.5 h? Express the answer as a whole number (in km). No need to write the unit.

Which best describes the motion of the object from 10 s to 15 s?

• It is not moving.

• It is moving at a constant speed.

• Its speed is increasing

• Its speed is decreasing.

What is the total distance (in meters) traveled by the object from t = 0 to t = 30 s? Express the answer as a whole number. No need to write the unit.

What is the average speed (in meters per second) of the object from t = 0 to t = 30 s? Express the answer in one decimal place. No need to write the unit.

What is the position (in meters) of the object at 25 s? Express the answer as a whole number. No need to write the unit.

Match the following average speeds

• Sandra

• 0.21 km/min

• Matt

• 0.30 km/min

• Andres

• 0.26 km/min
