Speed, Velocity, Acceleration Extension

Speed equals distance divided by

• time
• velocity
• size
• motion

When you know both the speed and direction of an object's motion, you know the

• average speed of the object
• acceleration of the object
• distance the object has traveled
• velocity of the object

The rate at which velocity changes is called

• speed
• direction
• acceleration
• motion

A train that travels 100 kilometers in 4 hours is traveling at what average speed?

• 50 km/h
• 100 km/h
• 2 km/h
• 25 km/h

If a bicyclist travels 30 km in 2 hours, her average speed is

• 30 km/h
• 60 km/h
• 15 km/h
• 2 km/h

The correct equation to calculate speed is

• distance/time
• time/distance
• distance x time
• distance/time²

Shona cycles at an average speed of 8km/h. How far has she traveled if she cycles for 4 hours?

• 55km
• 32km
• 43km
• 32miles

Find the velocity of a truck that travels 75 miles north in 2.5 hours.

• 187.5 mph north
• 30 mph north
• 300 mph north
• 200 mph north

It took 3.5 hours for a train to travel the distance between two cities at a velocity of 120 miles/hr.  How many miles lie between the two cities? 

• 34 miles 
• 420 miles
• 120 miles 
• 360 miles 

A car accelerates from a standstill to 70 m/s in 10 seconds.  What is the acceleration?

• 0.7m/s2
• 7m/s2
• 14m/s2
• none of the above
