What can be measured in meters per second (m/s)?

• Distance

• Time

• Speed

• Mass

What two measurements are necessary for calculating speed?

• Distance and time

• Speed and velocity

• Acceleration and distance

• Time and mass

What is the average speed of a person who walks 3 miles in 1 hour and then runs 3 miles in 30 minutes?

• 4 mph

• 5 mph

• 6 mph

• 7 mph

Cesar drove from Houston to Dallas in 4 hours. Dallas is roughly 250 miles NW of Houston. What was his average speed?

What is average speed?

• The total distance traveled divided by the total time taken.

• The speed at which an object moves in a straight line.

• The maximum speed reached by an object during its motion.

• The speed of an object at a specific moment in time.

If a runner completes a 5 km race in 25 minutes, what is their average speed in km/h?

• 10 km/h

• 12 km/h

• 14 km/h

• 15 km/h

What is the formula to calculate speed?

• S = d/t

• S = t/d

• S = d + t

• S = d - t

What is the relationship between distance, speed, and time?

• Distance = Speed + Time

• Distance = Speed - Time

• Distance = Speed x Time

• Distance = Speed / Time

What units are commonly used to measure speed?

• Kilometers per hour (km/h)

• Miles per hour (mph) and meters per second (m/s)

• Feet per second (ft/s)

• Yards per minute (yd/min)
